Question

F(x) = 2.5x - 10.5if X= 2

Answer 1

-5.5

Step-by-step explanation:

Gven the below function;

`f(x)=2.5x-10.5`

when x = 2, it means we should substitute x = 2 into the above function or find f(2);

`\begin{gathered} f(2)=2.5(2)-10.5 \\ =5-10.5 \\ =-5.5 \\ \therefore f(2)=-5.5 \end{gathered}`
