CPM Homework Help : CALC Problem 3-152

Find $z^\prime(x)$ if $z(x) = 3x^2 + 5x + 1$ . Then, find the equation of the tangent in point slope form at $x =-2$ .

Hint:

Hint 2:

To find $h$ and $k$ (the point): $h$ is given as $x =-2$ , therefore $k$ is $z(-2)$ .

Hint 3:

To find $m$ (the slope):evaluate $z^\prime(x)$ at $x =-2$ .
