(2x + 1) + (7x - 10) = 90. [WXY is a right angle]
9x - 9 = 90
9x = 99
x = 11
WXZ = 2x + 1 = 2 x 11 + 1 = 23 degrees

Hope this helps.
F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
