1. Evaluate f(x) = x^4 at x = -2 :

f(-2) = (-2)^4 = 2^4 = 16

2. Evaluate g(x) = 4x^2 at x = -2 :

g(-2) = 4(-2)^2 = 4 \cdot 4 = 16

Sincef(-2) = 16 and g(-2) = 16 , the given point ( -2, 16 ) satisfies both functions.

Answer: Yes, Isse's claim is true. The graphs intersect at the point(-2, 16) .

2. Evaluate

Since

Answer: Yes, Isse's claim is true. The graphs intersect at the point
