Use the given D to find the range of each function: a) g(x)=−3x+1, D={−2, 1, 4}
b)f(x)=2x+6, D={−5, −1, 4}
c)g(x)=5x−3, D={ −3, −2, −1}
d)f(x)=x−4, D={−2, −1, 3}

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 = 7g(1) = -3*1 + 1 = -2g(4) = -3*4 + 1 = -11R = {-11, -2, 7}

b)  f(x)=2x+6, D={−5, −1, 4}

f(-5) = 2(-5) + 6 = -4f(-1) = 2(-1) + 6 = 4f(4) = 2*4 + 6 = 14R = {-4, 4, 14}

c)  g(x)=5x−3, D={ −3, −2, −1}

g(-3) = 5(-3) - 3 = -18g(-2) = 5(-2) - 3 = -13g(-1) = 5(-1) - 3 = -8R= {-18, -13, -8}

d)  f(x)=x−4, D={−2, −1, 3}

f(-2) = - 2 -4 = -6f(-1) = -1 - 4= - 5f(3) = 3 - 4 = -1R = {-6, -5, -1}
