Using the graph calculator to graph the function f(x)=-√x. which list contain three points that lie on the graph of the function? (-9,,,1) (1,,,3) (-9,-,-,-1) (1,-,-,-3)

The list of points that lie on the graph of the function is:

                (1,-1),(4,-2),(9,-3)  

The square root function f(x) is given by:

We know that the domain of the square root function is x ≥ 0

and when x ≥ 0

then √x ≥ 0

Hence,

This means that the list of points must have x-coordinate as non-negative value and y-coordinate as non-positive value.

Now when x=1

we have:

when x=4 we have:

and when x=9 we have:

Hence, the points are:

(1,-1) , (4,-2) and (9,-3)

By plotting the graph of this function we may check the point.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
