Evaluate the function rule to find the range of each function for the domain {-3, 0, 5}.
f(x) = 4x − 9

a.
{-21, -9, 11}

b.
{-21, 9, 29}

c.
{-9, 3, 29}

d.
{3, 9, 21}

The range is ur f(x) values and ur domain is ur x values.

f(x) = 4x - 9...when domain (x) is -3
f(-3) = 4(-3) - 9
f(-3) = -12 - 9
f(-3) = - 21

f(x) = 4x - 9...when domain (x) = 0
f(0) = 4(0) - 9
f(0) = -9

f(x) = 4x - 9...when domain (x) is 5
f(5) = 4(5) - 9
f(5) = 20 - 9
f(5) = 11

so ur range is { -21,-9,11} <==
