FIND AN EQUATION OF THE TANGENT LINE TO THE GRAPH OF THE FOL
FIND AN EQUATION OF THE TANGENT LINE TO THE GRAPH OF THE FOLLOWING FUNCTION AT THE POINT (-3,-25)
 
-3x^2+2
-3x^2+2
Solution
f(x) = -3x2 + 2
First, the slope of the tangent line at (-3,-25) is given by
first finding the derivative.
f\'(x) = -6x
the slope is f\'(x) evaluated at x = -3.
m = -6*-3 = 18
The equation of the tangent line can be gotten by using the
point slope version of a linear function:
y - (-25) = 18(x - (-3))
y + 25 = 18(x + 3)
y = -25 + 18x + 54
y = 18x + 29
Which is your final answer.
