Is this a function or no function? Y=x2

Mathematics

ioda3 years ago
8 0
  In order to find out whether something is a function or not, you can choose to graph the equation or find out using other methods. If the equation passes the vertical line test, such that each x value has only one corresponding y value, then the equation is a function. In other words, something is a function only if each of its inputs has only one output. You can find out whether the equation is a function through substituting values into the equation or finding the table of the graph of the equation. The simplest method available if you have a graphing calculator is to just draw a straight line above any x-value. If there's only one point on the graph that has that x-value, then the equation you're talking about is a function. If not, then it's not a function.

Each day valerie charges her lunch account for her lunch. If the cost of lunch is $3 then by how much has her lunch account been
gavmur [86]

Answer: the amount by which her lunch account would have been impacted is $45

Step-by-step explanation:

Each day Valerie charges her lunch account for her lunch. If the cost of lunch is $3 then, it means that Valerie charges the lunch account with $3 daily. It means that in x days, she would have charged her lunch account with 3×x = $3x

If she charged her account for a period of 15 days, it means that x = 15. Therefore, the amount by which her lunch account would have been impacted is 3×15 = $45

Using property find <br>a.3/5×-2/7+4/5-3/10×2/7​
Sedaia [141]

Here the answer is 19/35

Step-by-step explanation:

\frac{3}{5} X\frac{-2}{7} +\frac{4}{5}-\frac{3}{10} X\frac{2}{7}

We will apply BODMAS rule

In this rule multiplication comes before add and subtraction

= \frac{-6}{35} + \frac{4}{5} - \frac{3}{35}

= \frac{4}{5} - ( \frac{6}{35}+ \frac{3}{35})

= \frac{4}{5} -  \frac{9}{35}

= \frac{4 X 7}{5 X 7} -\frac{9}{35}

= \frac{28}{35} - \frac{9}{35}

= \frac{19}{35}
