Question

X: -2, -1, 0, 1, 2, 3, 4

f(x): -29, -21, -13, -5, 3, 11, 19

20. Several vales of the function f are shown above. If f is a linear function and then function g is defined by g(x)= 2f(x)-1. What is the value of g(3)?

21. Given the function in question 20, what is the value of f(g3))?

Answer 1

Answer: 20. 21; 21. 155;

Explanation: In the first question substitute 3 for x and solve using distributive property. For the second one find f(21) using arithmetic series.
