If f(x) = -x + 8 and g(x) = x^4, what is (gºf)(2)?

kotykmax [81]

Answer:

$\large\boxed{(g\circ f)(2)=1296}$

Step-by-step explanation:

$(g\circ f)(x)=g\bigg(f(x)\bigg)\\\\f(x)=-x+8,\ g(x)=x^4\\\\(g\circ f)(x)=\g\bigg(f(x)\bigg)=(-x+8)^4\\\\(g\circ f)(2)\to\text{put x = 2 to the equation}\ (g\circ f)(x):\\\\(g\circ f)(2)=(-2+8)^4=(6)^4=1296$
