What is the domain of the function below?

djyliett [7]

${ x | x ≥ - 2}$

To get the domain of a function, the function must output a number that is not a division by zero or a square root of a negative number.

Also the graphs seemed to be like $\sqrt{x +2} -1$ .

If we let your graph be y

$y = \sqrt{x +2} -1$ This equation must be the graph.

If a function shouldn't output a square root of a negative number so it must be $x +2 ≥ 0$ so that there will be no negative number under the radical sign.

$x +2 ≥ 0 \\ x ≥ -2$

Also we can see that the graph has no y's for x's lesser than -2

Complete the equation of the line through (-9,7) & (-6,-3)

scZoUnD [109]

Answer:

$y=-\frac{10}{3}x-23$

Step-by-step explanation:

we have the points

(-9,7) and (-6,-3)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{-3-7}{-6+9}$

$m=-\frac{10}{3}$

step 2

Find the equation in point slope form

$y-y1=m(x-x1)$

we have

$m=-\frac{10}{3}$

$(x1,y1)=(-6,-3)$

substitute

$y+3=-\frac{10}{3}(x+6)$ ---> equation in point slope form

step 3

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$y+3=-\frac{10}{3}(x+6)$

Isolate the variable y

Distribute right side

$y+3=-\frac{10}{3}x-20$

subtract 3 both sides

$y=-\frac{10}{3}x-20-3$

$y=-\frac{10}{3}x-23$
