Answer:
Step-by-step explanation:
From the function, y = cos (3x)
Inputting values of x (horizontal axis), x = pi
y = cos (3 × pi)
= -1 ( remember you are dealing with values in radians not degree)
So now graph 1 and 3 have the same values. So inputting, x = pi/2 into the function, y = cos (3x)
= cos ((3 × pi)/2)
= 0

Answer:
y=3x-4 is the slope-intercept form of the equation of a line. It is in the form y=mx+b.
m is the slope (often called "rise over run") and b is the y-intercept (the point where x=0).
The y-intercept is the point (0,-4).
We need one other point. This is where finding easy calculations pays off. How about where x=2, y=(3)(2)-4 = 2.
That's the point (2,2).
