Question

Choose all that give the correct effect on the linear graph of the parent function ƒ(x).f(x) is replaced with f(x) + 5 shifts the line 5 units upf(x) is replaced with f(x − 8) shifts the line 8 units leftf(x) is replaced with 4f(x) stretch vertically by a factor of 4f(x) is replaced with f(3x) compress horizontally by a factor of 1/3

Answer 1

Since the parent function is f(x), then

f(x) + 5 is the shifted 5 units up of f(x)

Then the first answer is correct

f(x - 8) is shifted 8 units right of f(x)

Then the second answer is wrong

f(x) is replaced by 4f(x) means it stretched vertically by a factor of 4

Then the third answer is correct

f(x) is replaced by f(3x) means it compressed horizontally by a scale factor of 1/3

Then the fourth answer is correct
