For the function $h\left(x\right) = −3x^{2} − 11x + 4$, find the value of each expression below.

1. $h\left(0\right)$

   Hint (a):

   Substitute 0 for x and simplify.

   $h\left(0\right) = −3\left(0\right)^{2} − 11\left(0\right) + 4$

   Answer (a):

   $h\left(0\right) = 4$

2. $h\left(2\right)$

3. $h\left(−1\right)$

4. $h ( \frac { 1 } { 2 } )$

• int (d):

  Remember how to multiply fractions.

5. For what value(s) of $x$ does $h\left(x\right) = 0$?
