Manish writes the functions g(x)= 3 sqrt -x - 72 and h(x) = -(x + 72)^3 Which pair of expressions could Manish use to show that g(x) and h(x) are inverse functions?

Step-by-step explanation:

Given

Required

Show that they are inverse functions

For g(x) and h(x) to be inverse, then:

We have:

Replace x with h(x)

Substitute value for h(x)

Similarly;

Replace x with g(x)

Substitute value for g(x)

Recall that:

So:

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

its kind of blurry. can you put a clearer pic?
