A) −6,−2.4,0.8,1.2
B) −4.6,−1.4,1.8,2.2
C) −5.6,−2.4,1.8,2.2
D) −6.6,−1.4,0.8,1.2

Answer 1

To evaluate the function f(x) = 2x - 2 for specific values of x, substitute each value into the function.

Step-by-step explanation:

To evaluate the function f(x) = 2x - 2 for various values of x, substitute each value into the function:

For x = -1.8, f(-1.8) = 2(-1.8) - 2 = -3.6 - 2 = -5.6

For x = -0.2, f(-0.2) = 2(-0.2) - 2 = -0.4 - 2 = -2.4

For x = 0.9, f(0.9) = 2(0.9) - 2 = 1.8 - 2 = -0.2

For x = 1.6, f(1.6) = 2(1.6) - 2 = 3.2 - 2 = 1.2
