You can put this solution on YOUR website!
Note: please use parenthesis to write (-3x+5)/(7x+4) so it's clear what is being divided


f%28x%29+=+%28-3x%2B5%29%2F%287x%2B4%29


f%28x%2Bh%29+=+%28-3%28x%2Bh%29%2B5%29%2F%287%28x%2Bh%29%2B4%29 Replace every copy of x with (x+h)


f%28x%2Bh%29+=+%28-3x-3h%2B5%29%2F%287x%2B7h%2B4%29 Distribute


So the final answer is choice A
