Answer :
Answer:
- a) R = {-11, -2, 7}
- b) R = {-4, 4, 14}
- c) R= {-18, -13, -8}
- d) R = {-6, -5, -1}
Step-by-step explanation:
a) g(x)=−3x+1, D={−2, 1, 4}
- g(-2) = -3(-2) + 1 = 7
- g(1) = -3*1 + 1 = -2
- g(4) = -3*4 + 1 = -11
- R = {-11, -2, 7}
b) f(x)=2x+6, D={−5, −1, 4}
- f(-5) = 2(-5) + 6 = -4
- f(-1) = 2(-1) + 6 = 4
- f(4) = 2*4 + 6 = 14
- R = {-4, 4, 14}
c) g(x)=5x−3, D={ −3, −2, −1}
- g(-3) = 5(-3) - 3 = -18
- g(-2) = 5(-2) - 3 = -13
- g(-1) = 5(-1) - 3 = -8
- R= {-18, -13, -8}
d) f(x)=x−4, D={−2, −1, 3}
- f(-2) = - 2 -4 = -6
- f(-1) = -1 - 4= - 5
- f(3) = 3 - 4 = -1
- R = {-6, -5, -1}
