Question

Find each value if f(x) = 2x - 1 and g(x) = 2 - x2.9. f(0)10. f(12)12. f(-2)13. g(-1)11. g(4)14. f(d)riosol

Answer 1

If

$\begin{gathered} f(x)\text{ =2x-1} \\ \text{and} \\ g(x)=2-x^2 \\ \end{gathered}$

Then,

$\begin{gathered} 1.\text{ f(0)=2(0)-1 = -1} \\ 2.\text{ f(12) = 2(12)-1 = 23} \\ 3.\text{ f(-2) = 2(-2)-1= -5} \\ 4.g(-1)=2-(-1)^2=1 \\ 5.g(4)=2-(4)^2=-14 \\ 6.\text{ f(d) = 2(d) - 1 = 2d - 1} \end{gathered}$
