Answer:
f(x)-g(x)=5x^3-17x^2+4 which appears as option A
Step-by-step explanation:
Simply subtract the function's expressions as shown below, and combine like terms to express the final result:
![f(x)=7x^3-10x^2-5\\g(x)=2x^3+7x^2-9\\f(x)-g(x)=7x^3-10x^2-5-[2x^3+7x^2-9]\\f(x)-g(x)=7x^3-10x^2-5-2x^3-7x^2+9\\f(x)-g(x)=7x^3-2x^3-10x^2-7x^2-5+9\\f(x)-g(x)=5x^3-17x^2+4](https://tex.z-dn.net/?f=f%28x%29%3D7x%5E3-10x%5E2-5%5C%5Cg%28x%29%3D2x%5E3%2B7x%5E2-9%5C%5Cf%28x%29-g%28x%29%3D7x%5E3-10x%5E2-5-%5B2x%5E3%2B7x%5E2-9%5D%5C%5Cf%28x%29-g%28x%29%3D7x%5E3-10x%5E2-5-2x%5E3-7x%5E2%2B9%5C%5Cf%28x%29-g%28x%29%3D7x%5E3-2x%5E3-10x%5E2-7x%5E2-5%2B9%5C%5Cf%28x%29-g%28x%29%3D5x%5E3-17x%5E2%2B4)
I think it could be 40° or 130°. Im not 100% sure however because i dont know how much all the numbers add up to. It could either be 180° or 270°
Answer:
5
Step-by-step explanation:
f(x) = x +6
g(x) = x^2 - 5
g(-2) = ?
x= -2
g(x) = x^2 - 5
g(-2) = -2^2 - 5
g(-2) =4 - 5
g(-2) =-1
now;
f(g(-2)) = ?
f(x) = x +6
f(g(-2)) = x + 6
g(-2) = -1
f(g(-2)) = -1 + 6
f(g(-2)) = 5
