Step 1

Given :


f(x)=x^2

Required:


To\text{ shrink by a factor of }(1)/(2),\text{ shift 3 units right and 2 units up.}

The question did not state clearly if we are to shrink vertically or horizontally. So we will attend to both.

Step 2

A vertical shrink by a factor of 1/2


\begin{gathered} f(x)=x^2 \\ f(x)\text{ = }(1)/(2)x^2 \end{gathered}

Step 3

A vertical shrink by a factor of 1/2 and a shift 3 units to the right


f(x)=(1)/(2)(x-3)^2

Step 4

A vertical shrink by a factor of 1/2, a shift 3 units to the right, and a shift of 2 units up


f(x)=\text{ }(1)/(2)(x-3)^2+2

Step 5

A horizontal shrink by a factor of 1/2


f(x)\text{ = }2x^2

Step 6

A horizontal shrink by a factor of 1/2 and a shift 3 units to the right


f(x)=2(x-3)^2_{}

Step 7

A horizontal shrink by a factor of 1/2, a shift 3 units to the right, and a shift of 2 units up


f(x)=2(x-3)^2+2

Hence the answer will be

If the shrink is vertical by a factor of 1/2, a shift 3 units to the right, and a shift of 2 units up ;


f(x)=\text{ }(1)/(2)(x-3)^2+2

If the shrink is horizontal by a factor of 1/2, a shift 3 units to the right, and a shift of 2 units up ;


f(x)=2(x-3)^2+2
