The graph shows that the function is equal to y = 2cos(3x) + 1 because in the graph I notice that the table is (0, 3), (60°, -1), and (120°, 3). It shows that a is equal to 2, b is equal to 3, and c is equal to -1, making the function equal to y = 2cos(3x) + 1
a = 2
b = 3
c = 1

Answer: (5, -6)</h3>
The point (7,-6) means x = 7 and y = -6 pair up. Recall that y = f(x). So if y = -6, then f(x) = -6 as well when x = 7. So f(7) = -6
Compare f(7) with f(x+2). We see that x+2 = 7 must be true. Isolate x by subtracting 2 from both sides
x+2 = 7
x+2-2 = 7-2
x = 5
The new x coordinate is x = 5. The y coordinate stays the same.
If we were to plug x = 5 into f(x+2), we would get
f(x+2) = f(5+2) = f(7) = -6
The input x = 5 leads to the output f(x+2) = -6
Visually, the point (7,-6) has been shifted 2 units to the left to land on (5,-6)
