Question

Which function, when graphed, would includethe point (3,125)?Of(x)=f) = 252O f(x) - 5Of(x) = 25

Answer 1

we need to check each option repalcing x=3 to obtain 125

1.

`\begin{gathered} f(x)=x^5 \\ f(3)=3^5 \\ f(3)=243 \end{gathered}`

Wrong

2.

`\begin{gathered} f(x)=25x \\ f(3)=25(3) \\ f(3)=75 \end{gathered}`

Wrong

3.

`\begin{gathered} f(x)=5^x \\ f(3)=5^3 \\ f(3)=125 \end{gathered}`

Right, then the option is third

the we dont need to check last option
