1 = 20 (24-4(1)=20)
2 = 16 (24-4(2)=16)
5 = 4 (24-4(5)=4)
6 = 0 (24-4(6)=0)

$f(x)=x^2-81\\
y=x^2-81\\
x^2=y+81\\
x=\pm \sqrt{y+81}\\
f^{-1}(x)=\pm \sqrt{x+81}\\$

$f(x)=2x-6\\
y=2x-6\\
2x=y+6\\
x=\dfrac{1}{2}y+3\\
f^{-1}(x)=\dfrac{1}{2}x+3\\
f^{-1}(2)=\dfrac{1}{2}\cdot2+3\\
f^{-1}(2)=1+3\\
f^{-1}(2)=4$

I've done the y = equations but I don't know how to do this one.

Tems11 [23]

Consider the equation

$-10x-y=-20$

1) First row of the table

Set x=0 and solve as follows:

$\begin{gathered} -10(0)-y=-20 \\ \Rightarrow-y=-20 \\ \Rightarrow y=20 \end{gathered}$

The answer is y=20 and the pair x-y is (0,20)

2) Second row

Set x=1 and solve, as follows:

$\begin{gathered} -10(1)-y=-20 \\ \Rightarrow-10-y=-20 \\ \Rightarrow-y=-10 \\ \Rightarrow y=10 \end{gathered}$

The answers are y=10 and (1,10)

3) Third row.

Set y=0 and solve as follows:

$\begin{gathered} -10x-(0)=-20 \\ \Rightarrow-10x=-20 \\ \Rightarrow x=\frac{20}{10}=2 \\ \Rightarrow x=2 \end{gathered}$

The answers are x=2 and (2,0)
