The inverse of the function f of x is equal to 1 half x plus 10 is shown. h of x is equal to 2 x minus what number What is the missing value?

Since f⁻¹(x) = ½x + 10, find f by reversing that relationship: swap x and y, then solve x = ½y + 10 for y. This gives y = 2x − 20, so h(x) is 2x minus 20. The missing value is 20.
