Answer:
(Updated) g(x). I corrected my math and found out that I missadded g(x). I was explaining y-intercept was your starting point yet I didn't count the starting point for g(x), lol!
Step-by-step explanation:
Looking at the (x)'s, f(x) has a y-intercept of 6. Remember, your y intercept is what you are starting with. Moving on to the next one. g(x), if you do the math, the table goes up by 4. However this isn't the y-intercept. 0 is your starting point, so moving to the side, 2 is next to 0. This makes your y-intercept 2. In the next graph, h(x) (if you have the same one as me) the y-intercept is at 4. On a graph, the Y-intercept is where a point in your x axis meets your y-line. To find your Y-intercept, just go to a graph and mark wherever the line crosses with the y-line as a point. Next one, j(x). Again, your y-intercept is your starting point. In this equation, your starting number is 10. A way to remember how to spot your y-intercept is this.
f(x) = a (b)^x
Your (x) is your plug in.
Your a is your y-intercept, or starting point.
Your b is your multiplier.
The x is usually the variable, but it can hold an exponet with it.
I'm sorry I'm late still. I understand I edited this so it might not be the best but I did try and correct myself. If there is anyway you can tell me if I'm right please do, again I'm not a math expert tho ^-^
