f(x) equals 19 when x = 3
Explanation:
Here we have the following function:
[tex]f(x)=2x^2+1[/tex]
And want to know the output of the function when the input is [tex]x=3[/tex]. So let's substitute this x-values into the function:
[tex]f(3)=2(3)^2+1 \\ \\ f(3)=2(9)+1 \\ \\ \boxed{f(3)=19}[/tex]
Finally:
f(x) equals 19 when x = 3
