Answer:

A) y ≥ -4

Step-by-step explanation:

The range of a function basically represents all of the y values that a function encompasses (I hope that makes sense, if not, please let me know).

In this graph, since the parabola has a vertex at (1, -4), the range includes y values only greater than or equal to -4. The function does not include y values lower than -4. Therefore, the range must be y ≥ -4.

To find the linear equation, use the slope formula y = mx+b, where b is the value of the y-intercept and m is rise/run.

The line rises 1 unit and runs (left to right) -5 units. (you could also say the line runs -1 units and runs 5 units, they will both give the same answer). Rise/run, 1/-5 = -1/5.

The y-intercept is the y value where the line touches the y-axis. In this case, it is +1.

Plug the information into the equation. m = -1/5 and y = 1. y = -1/5x + 1

Step-by-step explanation:

We know that if (h,k) is the center of any circle and whose radius is = r then its equation is :

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$
