No it does not. Any function that has any of the same X vaules (The line going up left to right) is not a function.

Answer:

The graph doesn't represent a function.

Step-by-step explanation:

Consider the provided graph.

A graph is said to be a function if for each value of x we can get different y value or each input (x) has a single output (y).

Now, observe the graph.

The value x = -5 is related to more than one value of the y.

For x = -5 we have different y values.

For example (-5,0), (-5,1), (-5,2),(-5,3) all these values satisfy the graph. Thus the graph is not a function.

We can prove it by a vertical line test.

Vertical line test: If a vertical line intersects the graph more than once, then the graph is not a function.

Now if we draw a vertical line at x=-5 it will intersect the graph more than once, therefore, the provided graph is not a function.

Hence, the graph doesn't represent a function.

Jake drew an isosceles right triangle. What are the measures of the two acute angles? How do you know?
scoray [572]
SO you know that triangles add up to 180. A right angle equals 90 so 180-90=90. And an isosceles triangle means that 2 angles are congruent. SO 90/2 = 45. The measure of the 2 acute angles are 45

What is the length of the line segment whose endpoints are A(-1,9) and B(7,4) in the simplest radical form?
monitta

length : \sf \sqrt{89}

Explanation:

use the distance formula : \sf \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

  • using the formula:

\sf \rightarrow \sf \sf \sqrt{(7--1)^2+(4-9)^2}

\sf \rightarrow \sf \sf \sqrt{(8)^2+(-5)^2}

\sf \rightarrow \sf \sf \sqrt{64+25}

\sf \rightarrow \sf \sf \sqrt{89}

An auditorium has 30 rows of seats. The first row has 20 seats, the second row has 22 seats, the third row has 24 seats, and so
gayaneshka [121]
An = a1 + (n-1)*d
n = term to find = 30
a1 = first term = 20
d = common difference = 2

a30 = 20 + (30 - 1) * 2
a30 = 20 + 29 * 2
a30 = 20 + 58
a30 = 78

sn = (n (a1 + a30)) / 2
s30 = (30(20 + 78) / 2
s30 = (30(98) / 2
s30 = 2940/2
s30 = 1470 <===
