The function is f(x) = x³ − 4x² + 2. Then the slope at x = 3 of the function will be 3.
<h3>How to find the slope?</h3>The slope of a line or straight object is the ratio of how much amount of rise occurs in correspondence to the increment in the run.
Thus, we get:
Slope = rise/ run
The function is given below.
f(x) = x³ − 4x² + 2
A line passing through the same point that f(x) passes through at x = 3 with a slope equal to the limit.
Then the slope of the function is given by the differentiation. Then we have
Slope|₃ = 3x² − 8x
Slope|₃ = 3(3)² − 8(3)
Slope|₃ = 27 − 24
Slope|₃ = 3
