2-140.

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

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

Substitute 0 for x and simplify.

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

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

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

• See part (a).

• $h\left(2\right) = −30$

1. $h\left(−1\right)$

• Be careful of the signs when multiplying negative numbers.

• $h\left(−1\right) = 12$

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

• Remember how to multiply fractions.

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

$0 = −3x^{2} − 11x + 4$
