How do you find the coordinates of the stationary point on the graph of y equals x root(x plus 1)?
A stationary point is where the derivative of a function is equal to zero. Let's find it for f(x)= x(x+1)^.5. Using the product rule and power rule, we compute f'(x)=x(.5)(x+1)^-.5+(x+1)^.5=[x(.5)+(x+1)]/[(x+1)^.5]. We now set this equal to zero. We can now ignore the denominator because as long as the numerator equals zero and the denominator does not equal zero, the whole thing equals zero. So 0=x(.5)+(x+1)=.5x+x+1=1.5x+1-->1.5x=-1-->x=-1/1.5=-2/3. Note that x=-2/3 does not make the denominator zero, so we have found the only stationary point. Note that f(-2/3)=(-2/3)(-2/3+1)^.5=(-2/3)(1/3)^.5≈-0.3849. That's it.
What else can I help you with?
What does to graph a point mean?
Mark the position of the point on the graph according to the coordinates of the point that are given (or calculated).
What is the lowest point of y equals x squared?
If you mean the graph, then the lowest coordinates would be (0,0). Also known as the origin.
What does it mean on a graph when x equals 0?
When x = 0, the point that has (0, y) coordinates will be on the y-axis for any y.
How do you know if a point is a solution if you are looking at the graph?
To determine if a point is a solution on a graph, check if the point's coordinates (x, y) satisfy the equation of the graph. If the point lies on the curve or line representing the equation, it is a solution. For instance, if the equation is y = f(x), substitute the x-coordinate into the equation to see if it equals the y-coordinate. If it does, the point is a solution.
