Which of the following functions has the greatest y-intercept?

Question

anonymous · Answer

f(x)

x	y
−3	−27
−2	8
−1	−1
0	0
1	1
2	8


g(x) = 4 sin(4x) − 3

anonymous · Answer

I think f(x)'s highest y-intercept is 8, but not sure w. g(x)

amistre64 · Answer

let x=0, youll find the y intercept ...

amistre64 · Answer

y intercept of f is not 8 .. the x=-2 intercept would be 8 :/

4 sin (0) - 3? How do I find the highest y-intercept with g(x)?
My bad, I looked in the y section and 8 was the greatest number. What would that be?

amistre64 · Answer

... when x=0.

amistre64 · Answer

and since sin0 = 0 that will leave us with g=-3 for its y intercept

amistre64 · Answer

look at the table, when x=0, what is the value of y?

anonymous · Answer

0... so then g(x) has the greatest y-intercept?

amistre64 · Answer

f(0) = 0
g(0) = -3

which is higher:  0 or -3?

anonymous · Answer

Oops, sorry! I was thinking 3! lol
 f(x) is higher!
