3/10 is the answer
i am not sure if the answer is wrong i am sorry
Answer:
Options B and D.
Step-by-step explanation:
The general form of sine function
where, |A| is amplitude, is period, is phase shift and D is y-intercept.
The general form of cosine function
where, |A| is amplitude, is period, is phase shift and D is y-intercept.
In function,
Amplitude :
y-intercept : -1
In function,
Amplitude :
y-intercept : -1
In function,
Amplitude :
y-intercept : 0
In function,
Amplitude :
y-intercept : -1
Therefore, the correct options are B and D.
Answer:
A
Step-by-step explanation:
you can find the vertex of each equation and then compare to the graph
x = -b/2a
A) x = -(-9)/2(1); x = 9/2 or x = 4 1/2
plug 4 1/2 into equation as 'x' to find 'y'
y = (9/2)² - 9(9/2) + 20
y = 81/4 - 81/2 + 20
y = 81/4 - 162/4 + 80/4
y = -81/4 + 80/4
y = -1/4
the only option with a vertex at (9/2, -1/4) is A
