Question

Please help out with Functions? Will fan and medal!

Answer 1

Which of these functions has the greatest y-intercept?

Answer 2

To find y - intercept set x = 0 and solve for y, for the graph it's where the function crosses the y - axis.

Answer 3

What about for h(x)?

Answer 4

y=mx+b, b is the y - intercept here

Answer 5

Okay.. let's see..

Answer 6

One moment..

Answer 7

\[f(x)=4x+5\] \[0=4(0)+5.\] \[y=9\]

Answer 8

??

Answer 9

Set x = 0 and solve for y, y = 4(0)+5 -> y=5 or just read from y = mx+b

Answer 10

Ah! You're right, my mistake... I added 4 to the 0. 4(0) = 0. So yes, y = 5...

Answer 11

Now I do the same for h(x)?

Answer 12

you could but this question seems to be made for eyeballing it

Answer 13

Oh wow....

Answer 14

By the way is this for a test?

Answer 15

No, it's from the lesson's practice questions. It gives you the answer but I wanted to do it on my own
