Answer:
A
Step-by-step explanation:
Recall that for a function to be valid, each input value of x must give us one and only one unique output value for y.
in this case we can see that one of the data sets is (3,-1)
which means that an input of 3 gave an output of -1
but we also see that another data set (3,1)
in this case an input of 3 gave an output of 1.
Because the same x input gives 2 different y outputs, this is not a function.
the answer is A
Answer:
x= -3
Step-by-step explanation:
Look at the screenshot, it explains how I got the answer.
The primitive function for
is given by it's indefinite integral.
To calculate it, recall:


Let's begin


To find the costant, we just need to use the fact that 

Therefore,

12345678910111213
12 and 13 are consecutive numbers
12+13=25
hence, 12 and 13 are your answers
