Question

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

f(x)


x y

−3 −27

−2 8

−1 −1

0 0

1 1

2 8


OR


g(x) = 4 sin(4x) − 3


a) f(x)

b) g(x)

c) f(x) and g(x) have the same y-intercept

d) not enough info

Answer 1

y-intercept is a value of function, when x=0.

f(0) = 0

g(x) = 4 sin(4x) − 3
g(0) = 4sin(4*0) - 3 = -3

0>-3,
so a) f(x) has greater y-intercept.
