Question #e7f98
1 Answer
y = 3(1/4(x - 3
Explanation:
Consider this skeleton equation:
y = a(bx + c) + d
Amplitude is the a value, so plug it in for a in the equation:
y = 3(bx + c) + d
With the period you can find the b value using this equation:
period = 2
(use 2
Since you already know the period, plug it in to this equation and solve for b:
8
Now plug this b value into the skeleton equation:
y = 3(1/4(x + c)) + d
Phase shift of 3
y = 3(1/4(x - 3
Finally, the vertical shift of -4 is shifting the graph downward, which is the d value. Now plug it into the equation to get the final equation:
y = 3(1/4(x - 3
