$f(x) = 27$
To find the value of $f(x)$, we plug in $-3$ for $x$: $f(x) = (-3)^2 - 4(-3) + 6$ Evaluate the exponent first, according to order of operations: $f(x) = 9 - 4(-3) + 6$ Then, we multiply: $f(x) = 9 + 12 + 6$ Now, we add or subtract from left to right: $f(x) = 21 + 6$ Add one more time: $f(x) = 27$
