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.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
