Assuming this question associates "solutions" with "zeros", then the answer is

   x^2 + 2x + 3 

======

If we set x^2 + 2x + 3 to equal 0, we have

   x^2 + 2x + 3 = 0

The discriminant of this equation of the form ax² + bx + c = 0 is

   discriminant = b² - 4ac = 2^2 - 4(1)(3) = -8

The discriminant is negative, so there are no real solutions (the discriminant is under a square root in the quadratic equation; square root of a negative number is not a real number)

What is the equation of the line? Graph of a line in the coordinate plane through the origin and the point begin ordered pair 1
Margarita [4]

Here the line passes through (0,0) and (1,3).

First we need to find the slope , and for that we need to use the following formula

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

On substituting the values from the point, we will get

m=\frac{3-0}{1-0}=3

Now we will use slope intercept form, which is

y = mx+ b

Where m is the slope and b is the y intercept

And on substituting the values of x and y from the point (1,3) and slope, m = 3, we will get

3 = 3(1)+b

3=3+b

b =0

Substituting the values of m and b in the slope intercept form, we will get

y= 3x

Answer:

1 and 3 are irrational!!! The others are all rational

Step-by-step explanation:

1 and 3 are never terminating and they are not repeating, therefore, they are irrational! All the others are either terminal (they have a decimal that stops) or they are repeting and those repeting numbers can be written as a fraction, for example 0.2222... can be written as 2/9

Which equation has a graph that is a parabola with a vertex at (–1, –1)?
zzz [600]

y = {(x + 1)}^{2} - 1

The one is a vertical translation of the parent function to the left of one

f(x) = {x}^{2}

making it -1.
