Points:
(-2, 3) and (3, 0)
------------------------------------------------
Find the slope:
------------------------------------------------
Slope Intercept Form:
y = mx + b
m = slope
b = y-intercept
Slope = -3/5
Y-intercept = 9/5
Answer: y = -3/5 + 9/5
------------------------------------------------
Point Slope Form:
y - y1 = m(x - x1)
You can use either of the points.
Answer:
y - 3 = -3/5(x - 2)
or
y - 0 = -3/5(x - 3)

We have been given that a cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 11, the vertical shift is 9 units down, and the period of the function is . The graph of the function does not show a phase shift. We are asked to write the equation of our function.
We know that general form a cosine function is , where,
A = Amplitude,
= Period,
c = Horizontal shift,
d = Vertical shift.
The equation of parent cosine function is . Since function is reflected about x-axis, so our function will be
.
Let us find the value of b.
Upon substituting our given values in general cosine function, we will get:
Therefore, our required function would be .
