The sum of measures of angles A and B is 90°
Hence the angles are complementary
- As complementary angles have sum 90°
plug in -4 in for x. then solve.
h(-4)=1/2(-4)-1
h(-4)= -3
Answer:
Step-by-step explanation:
let : y = x² - 8
calculate : x
x² = y + 8
x exist : y + 8 ≥ 0
x = √(y + 8) or x = - √(y + 8)
conclusion :
if : x ≥ 0 the inverse of f(x) is : g(x) = √(x + 8)
if : x ≤ 0 the inverse of f(x) is : h(x) = - √(x + 8)
