Question

How do i evaluate the function p(x)=-x^5+11x^3+7 when x=3

Answer 1

To evaluate the function p(x) = -x^5 + 11x^3 + 7 when x = 3, you need to substitute 3 for x in the function and then perform the arithmetic operations.

p(3) = -(3)^5 + 11(3)^3 + 7

p(3) = -243 + 363 + 7

p(3) = 137

So, p(3) = 137
