Does this graph represent a function? Why or why not?

Answer:

No, because it fails the vertical line test

Step-by-step explanation:

The vertical line test can easily be used to determine if a graph represents a function or not. It is also very simple.

At any point in the graph, draw a vertical line. If the line intersects the graph more than once, the graph is NOT a function.

In your case, this graph fails the vertical line test, so it is not a function.

Hope this helps! Have a great rest of your day! :)

Answer:

c + (a + 1.70) = 6.70

Step-by-step explanation:

you start the equation by Subtracting how much more alan has to the total

(this will only be set as an equation do not actually solve it)

then add 1.70 to a

6.70 - 1.70 = a + c

(1.70 + a)

c + (a + 1.70) = 6.70 "

for any numbers x,y [x=0 in(4) and y = 0 in (5)] and any positive integers m,n, the following holds:x^m · x^n=x^m+nProve number

AlladinOne [14]

Proved

Explanation:

To prove x^m · x^n=x^m+n, let's assign numbers to x, m and n

let x = 2

m = 3, n = 4

x^m · x^n = 2^3 . 2^4

x^m+n = 2^(3+4)

Solve each of the above seperately and comparew the answer:

$\begin{gathered} x^m\times x^n=2^3\times2^4 \\ =\text{ (2}\times2\times2)\times(2\times2\times2\times2) \\ =\text{ 8}\times16 \\ =\text{ }128 \end{gathered}$ $\begin{gathered} x^{m+n}=2^{3+4} \\ =2^7\text{ = 2}\times2\times2\times2\times2\times2\times2 \\ =\text{ 128} \end{gathered}$ $\begin{gathered} sincex^m\times x^n\text{ = 128} \\ \text{and x}^{m+n}\text{ = 128} \\ \text{Therefore, }x^m\times x^n\text{ = x}^{m+n} \end{gathered}$

This expression x^m · x^n=x^m+n has been proved to be equal
