Steps:
3x - 2(0) = 6
3x = 6
X = 2

Plug 2 into the equation

3(2) - 2y = 6
6 - 2y = 6
6 = 6 + 2y
0 = y

If this is wrong try doing it the opposite way which is:

3(0) - 2y = 6
-2y = 6
Y = -3

3x - 2(-3) = 6
3x + 6 = 6
3x = 0
X = 0

Answer:

3x= 2y +6

and when we put y = 0

then 3x = 6

x = 6/3

x =2

SECOND one , when we put x = 0

0= 2y +6

-6 = 2y

-6/2= y

-3 = y

Which function is increasingnon the interval (negative infinity, positive infinity)
BlackZzzverrR [31]

Answer:

h(x) = 2^(x) - 1.

Step-by-step explanation:

Let's look at each equation:

f(x) = -3x +7, Well as x increases, since it's multiplication, there are "going to be more" -3's, so it's going to be decreasing.

g(x) = -4(2^x). While 2^x is increasing, because "there are going to be more 2's multiplied by each other" as x increases, it's being multiplied by a negative number, so it's actually going to be decrasing

h(x) = 2^(x) - 1. Here's it's going to be increases as x goes towards infinity because "there are going to be more 2's multiplied by each other", and there isn't any negative sign, while there is a negative 1, it's constant, so the overall value will be increasing
