22 questions
Evaluate the following functions when x = -3, 0, and 2. Write your answers as a list, with commas, but no spaces or brackets or parentheses. Example: 3,6,4
1

f(x) = 15x + 4

1

g(x) = -9x + 1

1

p(x) = -7x - 5

1

h(x) = 3.25x

1

m(x) = -4.4x

1

f(x) = 6.1x - 3.3

1

f(x) = -2.5x + 7

1

h(x) = 4.2x - 3

1

g(x) = 6.1x - 2.2

Find the value of x so that the function has the given value.
1

f(x) = 4x - 2; 18
(looking for the x value that would make the function equal to 18)

1

n(x) = 7x + 4; 39

1

q(x) = 6 - 5x; 21

1

g(x) = -3x + 8; 14

1

h(x) = 9x - 13; 23

1

m(x) = 12x - 30; 30

1

g(x) = -4x - 9; 3

1

m(x) = 8.5x - 3; 82

1

p(x) = -2.4x + 6; 18

1

d(x) = 3.3x - 1.1; 31.9
