What is the range of the function f(x) = 4x + 9, given the domain D = {-4, -2, 0, 2}?


A. R = {-17, -9, -1, 17}


B. R = {1, 7, 9, 17}


C. R = {-7, -1, 9, 17}


D. R = {-7, 1, 9, 17}

What is the range of the function fx 4x 9 given the domain D 4 2 0 2A R 17 9 1 17B R 1 7 9 17C R 7 1 9 17D R 7 1 9 17 class=

[tex]f( - 4) = 4( - 4) + 9 = - 7[/tex]

_________________________________

[tex]f( - 2) = 4( - 2) + 9 = 1[/tex]

_________________________________

[tex]f(0) = 4(0) + 9 = 9[/tex]

_________________________________

[tex]f(2) = 4(2) + 9 = 17[/tex]

Thus ;

R = { - 7 , 1 , 9 , 17 }
