Tangent slope of 4x^2+2x when x=-2

Mathematics
1 answer:
polet [3.4K]3 years ago
4 0

Answer:

-14

Step-by-step explanation:

f(x) = 4x² + 2x

Take the first derivative:

f'(x) = 8x + 2

Evaluate at x = -2:

f'(-2) = 8(-2) + 2

f'(-2) = -14

The tangent slope is -14.

-2 times g(4) when g(x) =-x squared+(4x)-11
andrezito [222]

Answer:

+22

Step-by-step explanation:

Given g(x) = -x^2 + 4x - 11, g(4) is -(4)^2 + 4(4) - 11, or just -11.

Then -2 times g(4) = -2(-11) = +22
