To solve a square root, get the ^2 on one side and the 81 on the other side.
add 81 to both sides.
c^2 = 81
to clear the power of 2, take the square root of both sides.
c = + - sqrt81
c = + - 9
c = 9 and c = -9
21X+7=2...........`\21X=2-7...........\ 21X=-5.............. X=-5÷21... this is the right answer..(x=-5÷21)

Answer:
OPTION C: h(x) = x - 3
Step-by-step explanation:
To find the inverse of the function y = x + 3.
Swap 'x' and 'y'.
We get x = y + 3.
Solve for 'y' now.
We get y = x - 3
Therefore, the inverse function becomes h(x) = x - 3.
