Step-by-step explanation
We are given the function

for part A
we are to find the derivative of the line tangent to the graph of f at x = 2
So, we will have

when x =2,

Thus, the slope at x is 20
For part B
To get the equation of the line tangent to the graph at x =2, we will substitute x =2 into f(x)

Thus, using the formula

Therefore, the equation is

Thus, the tangent line is: y= 20x -24
