Question

The parent function, f(x) = 5x, has been vertically compressed by a factor of one-half, shifted to the right three units and down two units.

Choose the correct function to represent the transformation.

Answer 1

g(x)=1/2(5x-3)+2

Explanation:

Just took the test :)

Answer 2

We are given the parent function, f(x) = 5x and is vertically compressed by a factor of 1/2, shifted to the right (3 units) and down two units.

Vertical compression makes the function:

f(x) = (1/2) * 5x

shifted 3 units to the right makes the function:

f(x) = (1/2) * 5 (x+3)

shifted 2 units down makes the function:

f(x) = (1/2) *(5 (x+3)) - 2

therefore, this function is the resulting function after performing all three adjustments of the parent function. First, compression, then shift to left/right, then shift up and down.
