\text{Hey there!}

\mathsf{3\dfrac{1}{2}\times3\dfrac{1}{2}=?}

\mathsf{3\dfrac{1}{2}=3\times2+1=6+1=7}\\\\\mathsf{7\ becomes\ your\ numerator\ \& \ 2\ stays\  as\ your\ denominator}

\mathsf{\dfrac{7}{2}\times\dfrac{7}{2}=?}

\mathsf{Numerator \rightarrow Numberator}

\mathsf{Denominator\rightarrow Denominator}

\mathsf{\dfrac{7\times7\leftarrow numerator}{2\times2\leftarrow denominator}}

\mathsf{7\times7=49}\leftarrow\mathsf{NUMERATOR}

\mathsf{2\times2=4}\leftarrow\mathsf{DENOMINATOR}

\boxed{\boxed{\mathsf{Answer:\dfrac{49}{4}\ or\ 12\dfrac{1}{4}}}}\checkmark

Part 1

<h3>Answer:   13</h3>

---------------------

Explanation:

We'll replace every copy of x with -3. Then use PEMDAS to simplify.

f(x) = -2x+7

f(-3) = -2(-3)+7

f(-3) = 6+7

f(-3) = 13

===========================================================

Part 2

<h3>Answer:  -11</h3>

---------------------

Explanation:

We work backwards in a sense compared to what part 1 did. Instead of finding f(x) based on x, we determine what x must be for a given f(x).

We'll replace f(x) with 29 and solve for x like so

f(x) = -2x+7

29 = -2x+7

-2x+7 = 29

-2x = 29-7

-2x = 22

x = 22/(-2)

x = -11

Note how if you replaced x with -11, we'd get,

f(x) = -2x+7

f(-11) = -2(-11)+7

f(-11) = 22+7

f(-11) = 29

which helps confirm we have the correct answer.
