Question

What is the range of y = 5x -2 if the domain is {-3, -1, 0, 1, 3}?
{-13, -3, 2, 3, 13}
{12, 3, 0, 3, 13}
{-17, -7, -2, 3, 13}

Answer 2

HEEELLLPPP

Answer 3

domain is all the x values and range is all the y values
we are given the domain (x values)
so sub in the x values to find the y values (the range)
y = 5x - 2.....when domain (x value) is -3
y = 5(-3) - 2
y = -15 - 2
y = -17...so when the domain is -3, the range is -17

next number
y = 5x - 2....when domain (x) is -1
y = 5(-1) - 2
y = -5 - 2
y = -7 .... so when the domain is -1, the range is -7

you see how I am doing this ?

Answer 4

kind of

Answer 5

so the answer would be C

Answer 6

just sub in your domain (x values) into the equation to find the rage (y values)

answer is C

Answer 7

ok thanks I have one more question

Answer 8

What is the solution set for the inequality 3x - 7 >9 if the replacement set is {-2, 0, 5, 7, 11, 13}?
{-2, 0, 5}
{7, 11, 13}
{-2, 0, 5, 7, 11, 13}
{0, 5, 7, 11}
