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.
The answer to this problem is A
Just use the division property of equality: divide 60 by -16 and you will get the value of x
B
The answer is, I already took this
