Question 119980


Let's evaluate {{{f(-2)}}}



{{{f(x)=5x+2}}} Start with the given function.



{{{f(-2)=5(-2)+2}}} Plug in {{{x=-2}}}. In other words, replace each x with -2.



{{{f(-2)=-10+2}}} Multiply 5 and -2 to get  -10



{{{f(-2)=-8}}} Now combine like terms



-----------Now let's evaluate another value---------



Let's evaluate {{{f(3)}}}



{{{f(x)=5x+2}}} Start with the given function.



{{{f(3)=5(3)+2}}} Plug in {{{x=3}}}. In other words, replace each x with 3.



{{{f(3)=+15+2}}} Multiply 5 and 3 to get  15



{{{f(3)=17}}} Now combine like terms



-----------Now let's evaluate another value---------



Let's evaluate {{{f(7)}}}



{{{f(x)=5x+2}}} Start with the given function.



{{{f(7)=5(7)+2}}} Plug in {{{x=7}}}. In other words, replace each x with 7.



{{{f(7)=+35+2}}} Multiply 5 and 7 to get  35



{{{f(7)=37}}} Now combine like terms
