Question

What transformation was not done to the linear parent function, f(x) = x, to get the function g(x) = - 1/2(x+5) +7

Answer 1

B; vertically compressed by a factor of 2

Explanation:

Here, we want to select from the options, the transformation procedure that was not applied

A. Shifted up by 7 units

This was applied

This can be seen through the +7 placed on the transformed equation

B. Vertically compressed by a factor of 2

This is wrong

The compression we had was intact to a tune of 1/2

So what this mean is that the compression we had for the equation was to a factor of 1/2 and not 2

c. This is correct

when we reflect over the x-axis; the y-axis value becomes negative

We had x before, but later we had -x

What this mean is for a reflection over the x-axis

d. Shifted right 5 units

This is correct

We had x before

a + 5 on x for the second equation actually validates the fact that the we have a shift to the right
