Question

F(x) = 1.8x – 10 and g(x) = −4.

Answer 1

-17.2

Step-by-step explanation:

`f(x) = 1.8x – 10 \\g(x) = −4.\\\\f=1.8x-10,\:g=-4,\:f\left(x\right)\:\circ \:g\left(x\right)\\\mathrm{For}\:f=1.8x-10\:\mathrm{substitute}\:x\:\mathrm{with}\:g\left(x\right)=-4\\\\=1.8\left(-4\right)-10\\=-17.2`
