2-140.

Substitute 0 for x and simplify.

h(0) = −3(0)2 − 11(0) + 4

h(0) = 4

See part (a).

h(2) = −30

Be careful of the signs when multiplying negative numbers.

h(−1) = 12

Remember how to multiply fractions.

0 = −3x2 − 11x + 4

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