Can someone explain how to do this?

Step-by-step explanation:

You have to make a table. Do this by taking each of the x values you see there and plug in for x into the equation and solve for y. Then plot the points.

x| -1  |  -2  |   -3   |   -4   |   -5   |

y|                                            

We will plug each x value in, do the math, and come up with y. The first x value is -1:

.  Do the math on that and you should get that y = 5. So one coordinate on this graph is (-1, 5).

At x = -2:

. Do the math on that and you should get that y = 2. Another coordinate on this graph is (-2, 2).

At x = -3:

. Do the math on that and you should get that y = 1. A third coordinate on this graph is (-3, 1).

At x = -4:

. Do the math on that and you should get that y = 2. A fourth coordinate on this graph is (-4, 2).

At x = -5:

. Do the math on that and you should get that y = 5. A fifth point on that graph is (-5, 5).

Plot all those points and connect the dots. This is a parabola-shaped graph because your equation is a second degree (quadratic).

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
