For the function $h(x)=-3x^2-11x+4$ , determine the following values.

$h(0)$
Hint (a):
Substitute $0$ for $x$ and simplify.
$h(0)=−3(0)^2−11(0)+4$
Answer (a):
$h(0)=4$

$h(2)$
Hint (b):
See part (a).
Answer (b):
$h(2)=−30$

$h(-1)$
Hint (c):
Be careful of the signs when multiplying negative numbers.
Answer (c):
$h(−1)=12$

$h\left(\frac{1}{2}\right)$
Hint (d):
Remember how to multiply fractions.

For what value(s) of $x$ does $h(x)=0$ ?
Hint (e):
$0=−3x^2−11x+4$
More Help (e):
