Given the domain values { -2, 0, 2 }, find the range values for the function y = 3x + 2.

Question

anonymous · Answer

3(-2)+2 = -4

3(0)+2= 2

3(2)+2 = 8

Range: $  (-4,2,8) $

ledah · Answer

I got the opposite of that 8,2-4 :/

ledah · Answer

could you answer another question for me please?

anonymous · Answer

That's the same thing, order doesn't matter in sets.

anonymous · Answer

In more general notation the answer is  $ \{ -4,2,8 \} $

ledah · Answer

Put the equation in slope-intercept form and identify the slope of the line. 3x + 9y = 12 (Nobody else answered this when i had it posted)

ledah · Answer

I dont quite know how to work this out

anonymous · Answer

$3x + 9y = 12$ This is a equation of straight line.

$ 3x + 9y = 12 \implies y = -\frac 13x+\frac 4 3 $

This is slope intercept form, where slope is $-\frac 13$
