Answer:

one x-intercept.

Transformation: shift to the right 8 units.

Step-by-step explanation:

The parent function is $f(t)=t^{2}$

To find the number of x-intercepts, we equate the function to zero.

$\implies t^{2}=0$

$\implies t=0$

There is only one x-intercept at t=0.

The transformed function is

$g(t)=(t-8)^2$

This function is obtained shifting the parent function 8 units to the right.

The x-intercept will now be at t=8.

Hence the image function also has one x-intercept.
