Answer:
one x-intercept.
Transformation: shift to the right 8 units.
Step-by-step explanation:
The parent function is
To find the number of x-intercepts, we equate the function to zero.
There is only one x-intercept at t=0.
The transformed function is
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.
