Answer:
y = -3cosx
Step-by-step explanation:
Let me rewrite your question:
- One x-intercept is ( pi/2 , 0) so we know that it is a trigonometric function such as cosine that has x-intercept (pi/2,0).
-
The maximum value is 3, it means the amplitude must be 3: y = 3 cos x
-
The y-intercept is (0,-3), means when x =0, y will equal to negative 3 (-3) then it is the function y = -3cosx,
So y = -3cosx is the function has the given properties
