The normal curve, or Gaussian distribution, approaches but never touches the axis because it is defined mathematically to extend infinitely in both directions. As you move further away from the mean, the probability density decreases, but it never actually reaches zero; instead, it asymptotically approaches the horizontal axis. This characteristic reflects the fact that while extreme values become increasingly unlikely, they are still possible, ensuring that the total area under the curve remains equal to one.
What else can I help you with?
Can you solve all quadratic equations?
NO!!!! On a graph a quadratic equation becomes a parabolic curve. If this curve intersects the x-axis in two places. then there are two different answers. If the curve just touches the x-axix on one place then there are two answers which both have the same valuer. If the curve does NOT touch the x-axis the there are NO solutions.
Where do you find the solutions to a quadratic equation on a graph?
The solutions to a quadratic equation on a graph are the two points that cross the x-axis. NB A graphed quadratic equ'n produces a parabolic curve. If the curve crosses the x-axis in two different points it has two solution. If the quadratic curve just touches the x-axis , there is only ONE solution. It the quadratic curve does NOT touch the x-axis , then there are NO solutions. NNB In a quadratic equation, if the 'x^(2)' value is positive, then it produces a 'bowl' shaped curve. Conversely, if the 'x^(2)' value is negative, then it produces a 'umbrella' shaped curve.
Why indifference curve never touches x axis or y axis?
Indifference curves represent combinations of two goods that provide the same level of utility to a consumer. If an indifference curve were to touch the x-axis or y-axis, it would imply that the consumer is indifferent to having zero quantity of one good, which contradicts the assumption of non-satiation—the idea that more of a good always provides greater utility. As such, consumers derive some level of satisfaction from both goods, preventing the curve from touching either axis.
What is the graph of an exponential decay function would have a curve upward along the x-axis towards negative infinity?
Your question seems very confused. The normal convention of the Cartesian coordinate system would place negative numbers below the x axis, so that any curve approaching negative infinity would curve downward, not upward.
How determine the area of curve under the x-axis?
Integrate the function for the curve, as normal, but the change the sign of the result. Be very careful that the curve is always on the same side of the x-axis between the limits of integration. If necessary, partition the integral. For example, to find the area between the x-axis and sin(x) between x=0 and x=3*pi, you will need Integral of sin(x) between 0 and pi, -[integral of sin(x) between pi and 2*pi] - this is where the curve is below the x-axis. +integral of sin(x) between 2*pi and 3*pi.
Why two tail of normal distribution do not touch the horizontal axis?
The domain of the Normal distribution is the whole of the real line. As a result the horizontal axis is asymptotic to the Normal distribution curve. The curve gets closer and closer to the axis but never, ever reaches it.
Does a normal curve ever intersect the x axis?
No
Do the Asymptotic means that the normal curve gets closer and closer to the X-axis but never actually touches it?
yes, an asymptote is a curve that gets closer but never touches the x axis.
Can you solve all quadratic equations?

If the curve just touches the x-axix on one place then there are two answers which both have the same valuer. If the curve does NOT touch the x-axis the there are NO solutions.
Why two trails of normal distribution do not touch the horizontal axis?
because it is imposible

Distinguish between demand curve and engel curve?
The difference is the Y- axis. In the case of the Demand curve the Y - axis is the retail price of the good. On the Engel's curve the Y -axis is the amount of income over a set period of time.
What is typically displayed on the x-axis of a solubility curve?
Temperatures are usually written on the x-axis of a solubility curve. Grams per 100 grams of water is usually shown on the y-axis.

Why two tails of the normal probability distribution extend indefinitely and never touch the horizontal axis?
This is because the normal distribution has a domain that extends to infinity in both directions.
How do you find the area between a given curve and x-axis?
Take the definite integral (and your bounds should be the two places where the curve crosses the x-axis).
