Answer:
<em>y = - cos ( </em>
<em> x + </em>
<em> ) </em>
Step-by-step explanation:
y = A cos ( Bx + C) + D
Vertical shift D = 0
A = - 1
Compression / Stretching B
Period of given function is 
Period of cos x is 2π
= 
⇒ B =
Horizontal shift is C ÷ B
Horizontal shift of given function is 
= C ÷ ⇒ C =
So, the equation of given function is
<em>y = - cos ( </em><em> x + </em><em> ) </em>

First, change it into general form(y=my+b).
3y=6x-1+10
3y=6x+9
y=2x+3
So, the slope is 2, and the y-intercept is 3
54+x=12+3x

Answer:
your answer is correct for the reason you state
Step-by-step explanation:
A one-to-one function must pass the horizontal line test: no horizontal line intersects the graph at more than one place.
Here, the horizontal line y=3 intersects at x=1 and x=2, so the test fails.
