Question

Given f(x) = x − 7 and g(x) = x2 Find f(g(−1)). f(g(−1))

Answer 1

$HEYA \: \\ \\ f(x) = x - 7 \\ g(x) = x {}^{2} \\ \\ g( - 1) = ( - 1) {}^{2} \\ \\ g( - 1) = 1 \\ \\ f(g( - 1) = g( - 1) - 7 \\ \\ f(g( - 1)) = 1 - 7 \\ \\ f(g( -1) = - 6 \\ \\ f(g( - 1)) \times f(g( - 1)) = - 6 \times - 6 = 36$
