Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(−2)

Step-by-step explanation:

Evaluate h ⋅ g

Replace the function designators in h ⋅ g with the actual functions.

Multiply by x by adding the exponents.

Evaluate h ⋅ g at −2.

Simplify

subtract 16 from -16

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
