Question

Compare the functions shown below:

f(x) = -3x − 5

h(x) = 2 cos(2x − π) + 4

Answer 1

g(x)

Answer 2

Which function has the greatest y-intercept?

f(x)

g(x)

h(x)

All three functions have the same y-intercept.

Answer 3

So, the y intercept is where x=0
on g(x) we can look at the graph and know it is -3
\(f(0)=-3(0)-5 \rightarrow -5\)
\[h(0)=2\cos(0-\pi)+4 \rightarrow-2+4\rightarrow2\]
so we have
f(0) = -5
g(0) = -3
h(0) = 2

Answer 4

@agreene Thank you soo much!
