y = -x^2

Step-by-step explanation:

First off you can tell that the graph represents a negative,

nonlinear function due to the direction of the 2 "lines" from

point (0,0). This simply means you can eliminate the graph

representing y = 2x^2 as one of the choices. Now as this is

squared function (^2) you can tell that every x value should be

squared to receive the y value. Here I am suggesting a simple

- x^2 to be defined for the graph.  Take x = 1 as the first

example. If x is squared then y is equal to 1 as well. This is

represented as two coordinates on the graph, when the y value

is negative and when the y value is positive. Now say x = 2.

When x is squared  y = 4, represented by the graph as two

points as well, when y is a negative value of 4 and a positive.

This shows that the graph resembles the function -x^2                             (y = -x^2)

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
