Question:
Solution:
1) if
[tex]f(x)=x^2-2[/tex]
then :
[tex]f(-3)=(-3)^2-2\text{ = 9-2 = 7}[/tex]
and
[tex]f(0)=0^2-2\text{ = 0-2 = -2}[/tex]
2) if
[tex]g(x)=3x+1[/tex]
then
[tex]g(4)=3(4)+1\text{ = 12+1 = 13}[/tex]
and
[tex]g(-2)=3(-2)+1\text{ = -6+1 = -5}[/tex]
3) if
[tex]h(x)=3^x[/tex]
then
[tex]h(3)=3^3=\text{ 3 x 3 x 3 = 27}[/tex]
and
[tex]h(-1)=3^{-1}\text{ = }\frac{1}{3}\text{ = 0.33}[/tex]
