Composition of Functions · Exercise 3

Find the value of a function.

For the function $f\left(x\right)=2x^2+3x+1$, find

ⓐ $f\left(3\right)$
ⓑ $f\left(–2\right)$
ⓒ $f\left(t\right)$
ⓓ The value(s) of x that make $f\left(x\right)=1$

Its source prints no answer for this problem, so there's nothing to check against.
