The y-intercept is the value of the function when 'x' is zero. That is, it's the point at which the graph of the function intercepts (crosses) the y-axis. The x-intercept is the value of 'x' that makes the value of the function zero. That is, it's the point at which 'y' is zero, and the graph of the function intercepts the x-axis.
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
It can be casually called the x intercept, but it/they is/are the root(s) of the function represented by the graph
-1
It is the y-coordinate of the intercept (the x-coordinate being 0).
An exponential function is a nonlinear function in the form y=ab^x, where a isn't equal to zero. In a table, consecutive output values have a common ratio. a is the y-intercept of the exponential function and b is the rate of growth/decay.
The x-intercept is the point at which a graph or function intersects the x-axis. It is the value of x when y is equal to zero on the graph.
The y-intercept is the value of the function when 'x' is zero. That is, it's the point at which the graph of the function intercepts (crosses) the y-axis. The x-intercept is the value of 'x' that makes the value of the function zero. That is, it's the point at which 'y' is zero, and the graph of the function intercepts the x-axis.
f(x)=2X-2
The graph of an exponential function f(x) = bx approaches, but does not cross the x-axis. The x-axis is a horizontal asymptote.
It is an exponential function.
An x-intercept is the point where a function intersects the x-axis on a Cartesian coordinate plane. For example, if the graph of a parabola is plotted and the graph intersects the x-axis on the coordinate plane, the point(s) where the graph intersects the x-axis are the x-intercepts for that function.
An exponential function is of the form y = a^x, where a is a constant. The inverse of this is x = a^y --> y = ln(x)/ln(a), where ln() means the natural log.
Depending on the graph, for a quadratic function the salient features are: X- intercept, Y-intercept and the turning point.
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
It can be casually called the x intercept, but it/they is/are the root(s) of the function represented by the graph
The x- and y-intercepts of a function are the points at which the graph of the function crosses respectively the x- and y-axis (ie. y=0 and x=0).
