Which graph shows the system StartLayout Enlarged left-brace 1st row x squared + y = 2 2nd row x squared + y squared = 9 EndLayout?

Graphs can be used to represent functions.

See attachment for the graphs of and

The functions are given as:

Rewrite as:

The above equation represents a circle of radius 3, and that has its center as the origin.

Similarly, we have:

Make y the subject

Rewrite as:

The above is a square function, that is reflected over the y-axis, and then shifted up by 2 units.

Step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
