What are the phase shift and period for the function y = 3cos[4(θ + 60°)] − 2?

1 answer:

5 0

The plus sign inside the parenthesis indicates that the shift is to the left, And the formula for the period is 2pi/B and our B is 4, so 2pi/4 = pi/2 which is 90. So your answer is the third one down, left 60 period 90

1. Find the slope and the y-intercept

Dvinal [7]

Answer:

c) slope: -7 ; y-intercept: 2

Step-by-step explanation:

Note the slope intercept form:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

Note in this case:

y = (-7)x + 2

y = y

m = -7

x = x

b = 2

c) slope: -7 ; y-intercept: 2 is your answer.
