Evaluate or estimate each expression based on the following table. 𝑥 −3 −2 −1 0 1 2 3 𝑓(𝑥) 1 2 4 2 1 0.5 0.25 a) 𝑓(0) b) 𝑓(2) c) 𝑓(1) − 𝑓(−1) d) 𝑓(1)𝑓(−2) Solutions: For each part, remember that the quantity in the parentheses after the 𝑓 is an 𝑥 -value (an input value), and you want to find the corresponding output value. To do this, just look along the first row of the table until you find the input value you

Unformatted text preview: looking for, and then see what output value goes with it (the number that’s directly below it is the output value). For parts a) and b), ±(0) = 2 and ±(2) = 0.5 . For part c), ±(1) = 1 and ±(−1) = 4, so ±(1) − ±(−1) = 1 − 4 = −3 For part d), ±(1) = 1 and ±(−2) = 2 , so ±(1)±(−2) = (2)(1) = 2...
