Answer: $f(2)=25$

Step-by-step explanation:

You know that the given function is:

$f(x)=4x^3-x^2-5x+7$

You know that you must evaluate this function for $x=2$ .

Then, to evaluate the function for $x=2$ , you need to substitute this value into the given function and simplify it.

Therefore, you get:

$f(x)=4x^3-x^2-5x+7\\f(2)=4(2)^3-(2)^2-5(2)+7\\f(2)=4(8)-(4)-10+7\\f(2)=32-4-10+7\\f(2)=25$

So, the answer is: $f(2)=25$

y = 5x - 4

Answer:

$- 8 {y}^{3} + 6 {y}^{2}$

Step-by-step explanation:

$2y^2(-6y + 3) + 4y^3 \\ \\ = - 12 {y}^{3} + 6 {y}^{2} + 4 {y}^{3} \\ \\ = 4 {y}^{3} - 12 {y}^{3} + 6 {y}^{2} \\ \\ = - 8 {y}^{3} + 6 {y}^{2}$
