Question

Given f(x)=3x+5
f(5)
how do u solve these

Answer 1

replace \(x\) by \(5\) and compute
\[f(5)=3\times 5+5\]

Answer 2

you have a function containing x
you want a function containing 5
so if you look how you have
f(x)=3x+5
f(5) would be instead of x's you would have 5's
so you are replacing all x's with 5

Answer 3

alrighty thanks yall
