Diketahui : f(x) = x+4g(x) = x^2-4h(x) = x-5Tentukan (fo(goh))(x) ?​

Jawab:

x² – 10x + 25

Penjelasan dengan langkah-langkah:

begin{aligned}(fcirc gcirc h)(x)&=f(g(h(x)))\&=f(g(x-5))\&=fleft((x-5)^2-4right)\&=fleft(x^2-10x+25-4right)\&=fleft(x^2-10x+21right)\&=x^2-10x+21+4\&=boxed{boxed{x^2-10x+25}} end{aligned}
