F(x)=9x^3+2x2-5x+4 and g(x) =5x^3-7x+4.what is f(x)-g(x)?

show all steps and final answer

The answer is 4x^3 + 2x^2 + 2x

Step-by-step explanation:

To find a subtracted function, simply change all of the signs in the second function and then combine like terms.

f(x) - g(x) = 9x^3 + 2x^2 - 5x + 4 - 5x^3 + 7x - 4

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

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.
