Question

Hi, can anyone help?

Answer 1

C.

Explanation:

Because when you first graph f(x)={x²+2,x<0} As shown in the first image the line is slanted to 2 in y axis just like Option C in the blue line and when you graph f(x)={-√x, x≥0} As shown in the second image the line is slanted down from 0 in x axis just like Option C in red line

Answer 2

c

Explanation:

The first equation is for a parabola but with x less than zero, so half a parabola on the negative side.

The second equation is -1*the square root of x. It will always be a negative number since you cant get a negative from a square root.

d and c are similar, but c has the half parabola on the correct side.
