CASE A: Discrete Domain, Limited Number of Points f(x) = 3x 1.Compute f(x) for each of the values in the domain. f(-2) = 3(-2)^{2} +6(-2) - 2 = -2f(-1) = 3(-1) ^{2} +6(-1) - 2 = -5f(0) = 3(0) ^{2} +6(0) - 2 = -2f(1) = 3(1) ^{2} +6(1) - 2 = 7f(2) = 3(-2) ^{2} +6(2) - 2 = 22 2. Mark down all the values that you obtained in the computations. |
CASE B: Continuous Domain, Infinitely Many Points-Interval
f(x) = x 1. Graph the function by hand or use Desmos.com. 2. Read the range from the graph, starting from the lowest 3.Write the range in the format: y E (-0.25, 6] |

CONCEPT CHECK:
When f(x) = x^{3} +2x^{2} -3x + 1, f(-1) is:
