Answer:
The x-intercept for f(x) is the constant in the f–1(x) equation.
Step-by-step explanation:
The x-intercept refers to the point where the graph of a function crosses the x-axis. At this point, the value of y is usually zero.
Consider a function;
[tex]f(x)=2x+3[/tex]
The x-intercept of this function is determined by replacing f(x) with 0 and solving for x. For this function the x-intercept is;
[tex]-\frac{3}{2}[/tex].
Now, the inverse of the function is evaluated by substituting f(x) with x and x with y in the original function and then solve for y;
[tex]x=2y+3[/tex]
[tex]y=\frac{x}{2}-\frac{3}{2}[/tex]
Clearly, The x-intercept for f(x) is the constant in the f–1(x) equation.
