Question

compare the functions shown below: f(x) = −3x − 5 g(x) cosine function with y intercept at 0, negative 3 h(x) = 2 cos(2x − π) 4 which function has the greatest y-intercept? (2 points) f(x) g(x) h(x) all three functions have the same y-intercept.

Answer 1

f(x) = -3x -5 has y-intercept of -5
g(x) has y-intercept of 0
-3hx = 2 cos (2x - π) + 4 => h(x) = -2/3 cos (2x - π) - 4/3

g(x) has the greatest y-intercept.

Answer 2

If the Question is:

f(x) = −3x − 5

g(x) =  

cosine function with y intercept at 0, negative 3

h(x) = 2 cos(2x − π) + 4

Which function has the greatest y-intercept?

a. f(x)

b. g(x)

c. h(x)

d. all three functions have the same y-intercept

Then the Answer is C. h(x)
