For the function f(x)= X^2-4, find the equation of the tangent line at X=12

y = 24x - 148

Step-by-step explanation:

Equation of the tangent line is a straight line which can be modeled by the general equation of y = mx + c

To find the gradient (m) of this function we must first differentiate our original equation and then substitute in our x = 12.

We are only given an x coordinate, so we will substitute this into our original equation to find a y coordinate.

To find c we will substitute in x, y, and m into y = mx+c, and then solve for c.

Plug in the gradient and c into the general equation for our answer.

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
