Question

if f(x)=2x^3-4x^2+2,and g(x)=x^3-2x^2-2x+4 then f(x)-g(xl=​

this answer in set notation which I don't get

Answer 1

Answer:

• x^3 -2x^2 + 2x -2
• c(2) = - 4

Step-by-step explanation:

Given

• f(x)=2x^3 - 4x^2 + 2
• g(x)=x^3 - 2x^2 - 2x + 4

To find

• f(x)-g(x)

Solution

• f(x)-g(x)=
• 2x^3 - 4x^2 + 2 - (x^3 - 2x^2 - 2x + 4) =
• 2x^3 - 4x^2 + 2 - x^3 + 2x^2 + 2x - 4 =
• x^3 -2x^2 + 2x -2

==================

• c(x) = -2x
• c(2) = -2*2 = - 4
