2-140.

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

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

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

$h\left(−1\right)$

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

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

int (d):
Remember how to multiply fractions.

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

Hint (e):

$0 = −3x^{2} − 11x + 4$

More Help (e):

Start with the diamond problem and factor using a generic rectangle.
