Question

calcule a função composta g(h(x)).
g(x)=x²+4 e h(x)=x-1

Answer 1

$g\left(x \right )=x^{2}+4\;\text{ e }\;h\left(x\right)=x-1\\ \\ \\ g\left(h\left(x \right ) \right )=\left(h\left(x \right ) \right )^{2}+4\\ \\ g\left(h\left(x \right ) \right )=\left(x-1\right )^{2}+4\\ \\ g\left(h\left(x \right ) \right )=x^{2}-2x+1+4\\ \\ g\left(h\left(x \right ) \right )=x^{2}-2x+5$
