For the function h(x) = −3x² − 11x + 4, find the value of each expression below. Homework Help ✎
1. h(0)
2. h(2)
3. h(−1)
5. For what value(s) of x does h(x) = 0?

Hint (a):

Substitute 0 for x and simplify.

h(0) = −3(0)² − 11(0) + 4

Answer (a):

h(0) = 4

Hint (b):

See part (a).

Answer (b):

h(2) = −30

Hint (c):

Be careful of the signs when multiplying negative numbers.

Answer (c):

h(−1) = 12

Hint (d):

Remember how to multiply fractions.

Hint (e):

0 = −3x² − 11x + 4
