explain how the graph of y=-2sin(x)-1 differs from the parent function. Make sure to compare key points used for graphing
Anna35 [415]
You can obtain the graph of the function y=-2sinx-1 from the graph of the function y=sinx making such transformations:
1.  <span>the multiplication by -2 increases y value twice and then  symmetrically reflects the graph y=2sinx about the x-axis;</span>
2. adding -1 to the  <span>y=-2sinx you translate the graph 1 unit down.
</span><span>
</span><span>On the added picture black line is a graph of y=sinx and red line is a graph of y=-2sinx-1.</span>

Check:
1. When x=0, y=-2sin0-1=-1;
2. When x= \frac{3\pi}{2}, then y=-2\sin  \frac{3\pi}{2} -1=-2(-1)-1=2-1=1.

Clara's utility function u(x,y)=(x+2)(y+1). write n equation for clara's indifference curve that goes through the point (x,y)=(2
professor190 [17]

we are given equation as

u(x,y)=(x+2)(y+1)

clara's indifference curve that goes through the point (x,y)=(2,8)

we can plug x=2 , y=8

u(x,y)=(2+2)(8+1)

u(2,8)=36

now, we can set it equal

we get

36=(x+2)(y+1)

now, we can solve for y

\frac{\left(x+2\right)\left(y+1\right)}{x+2}=\frac{36}{x+2}

y+1=\frac{36}{x+2}

y=\frac{36}{x+2}-1..........Answer
