Step-by-step explanation:

Substitute the value of x in the equation with each of the x's given in the table.

Example:

When x = -1

y = -1^2 - 4 x -1 = 1 - 4 = -3

When x = 4

y = 4^2 - 4 x 4 = 16 - 16 = 0

Select the correct answer.
larisa [96]

Answer:

B

Step-by-step explanation:

In this graph we can see a "Parabola", this is the curve for a second degree polynomial function, and based on "Fundamental theorem of algebra" we can know that this polynomial has 2 roots (they can be real or imaginary).

In this graph, the curve doesn't touch the X axis, so we know that this function has not real root. So both roots are complex

NISA [10]

Answer:

1 : a set each of whose elements is an element of an inclusive set. 2 : division, portion a subset of our community.

Step-by-step explanation:

In mathematics, set A is a subset of a set B if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be equal; if they are unequal, then A is a proper subset of B. The relationship of one set being a subset of another is called inclusion

The table shows a linear relationship between x and y
irga5000 [103]

We have been given a table that shows a linear relationship between x and y. We are asked to find the rate of change change of y with respect to x.

To solve our given problem, we will find the slope of the line passing through the given points.

m=\frac{y_2-y_1}{x_2-x_1}

Let us find slope of line using points (-20,96) and (-2,15).

m=\frac{15-96}{-2-(-20)}

m=\frac{-81}{-2+20}

m=\frac{-81}{18}

m=-4.5

Therefore, the rate of change of y with respect to x is -4.5.
