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

OpenStudy (anonymous):

where is f?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

f(x) = 3x2− 4. 3x^2 ?? like this?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

O ok thanks I got the same thing to.

good job
