I think you have to pull out a -1 from the expression under the radical:

5 \sqrt{-x+32} =30 \\ 5 \sqrt{-(x-32)} =30

Which function will have a y-intercept at –1 and an amplitude of 2?
Angelina_Jolie [31]

Answer:

Options B and D.

Step-by-step explanation:

The general form of sine function

h(x)=A\sin (Bx+C)+D

where, |A| is amplitude, \frac{2\pi}{B} is period, \frac{-C}{B} is phase shift and D is y-intercept.

The general form of cosine function

h(x)=A\cos (Bx+C)+D

where, |A| is amplitude, \frac{2\pi}{B} is period, \frac{-C}{B} is phase shift and D is y-intercept.

In function, f(x)=-\sin x-1

Amplitude : |A|=1

y-intercept : -1

In function, f(x)=-2\sin x-1

Amplitude : |A|=2

y-intercept : -1

In function, f(x)=-\cos x

Amplitude : |A|=1

y-intercept : 0

In function, f(x)=-2\cos x-1

Amplitude : |A|=2

y-intercept : -1

Therefore, the correct options are B and D.
