Expert Solution
Step 1

To determine the value of x for which the given function have slope 6.

4x3
+2x27x-21
f(x)=
Step 2

In order to find the slope of the given function, we must find the first derivative of the given function.

Therefore,

d
By applying the Power Rule
dx
(x°)=a-x
d(f(x))_ 4
.3x31 2-2x21 +7-0
3
dx
= 4x2 +4x +7
