F(x)=2x 2 +2x−1andg(x)=x 2 +5x+3find the value of x |

Answer» This is a composite FUNCTION.Concept: For such a function, i.e g(f(x)), perform INNER, and then outer. This means evaluate f(x) FIRST. The value will be known as value V. Then perform g(V).Essentially, g(f(x))= g(V), where f(x)= V where x and V are valuesApplication:Inner: f(-1)= 2(-1)-1 = -2–1=-3Outer: g(-3)= (-3)^2 + 3= 9+3= 12Answer: 12Hope this helps.Step-by-step explanation:pls mark me as a brainlest |
