So I Am Struggling In Math And I Could Use Some Help To Try And Get Through It class=

Sagot :

Given the functions:

[tex]\begin{gathered} f(x)=-5x+2 \\ g(x)=-2x²-3 \end{gathered}[/tex]

to find f(7), we can make x = 7 on the function f to get the following:

[tex]\begin{gathered} f(7)=-5(7)+2=-35+2=-33 \\ \Rightarrow f(7)=-33 \end{gathered}[/tex]

in a similar way, we can find g(5) by making x = 5 on the function g:

[tex]\begin{gathered} g(5)=-2(5)²-3=-2(25)-3=-50-3=-53 \\ \Rightarrow g(5)=-53 \end{gathered}[/tex]

therefore, f(7) = -33 and g(5) = -53
