Question

b. Find the equation of the tangent line to the graph of f at the point (−2, 8).

Answer 1

where is f?

Answer 2

well the question above it said Let f be the function defined as f(x) = 3x2
− 4. 3x^2
a. Use the definition of the derivative to find f′(x)
b.and my anserw was 6x

Answer 3

f(x) = 3x2− 4. 3x^2 ?? like this?

Answer 4

no \[f(x)=3x^2-4\]

Answer 5

f'(x) =6x
f'(-2)=6(-2) =-12
so line equation is: y+2=-12(x-8)

Answer 6

O ok thanks I got the same thing to.

Answer 7

good job
