Answer:
4a^3
Step-by-step explanation:
Please check the attached photo.
For this case we evaluate the function when x = 0
We then have to evaluate:
y = -2sinx - 1
y = -2sin (0) - 1
y = -1
Then, the intersection with the y-axis is -1 and the amplitude is 2.
Answer:
y = -2sinx - 1
option 2
The formula to find the x coordinate is -b/2a. If you plug in the variables
-5/2(2) = -5/4 = -1.25
x = -1.25
Now plug in x into the y equation.
y = <span>-11.125</span>
