Question

Which function is the result of vertically shrinking ƒ(x) = x2 by a factor of 1∕3 and translating it to the right 7 units?

Answer 1

Answer:

B) Y = 1/3 (x-7)^2

Step-by-step explanation:

To vertically shrink the function by a factor of 1/3, we just need to multiply it by the factor, that is:

$y = (1/3) * f(x)$

$y = (1/3) * x^2$

$y = x^2 / 3$

Now, to translate the function 7 units to the right, we just need to substitute the values of x in the function by (x-7):

$y = (x-7)^2 / 3$

So the correct option is B)
