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
<u>Answer:</u>
The correct answer option is A. positive.
<u>Step-by-step explanation:</u>
When an exponent or a power is an even number and the base is a negative number, the value is always positive.
Suppose we have a negative base
and a power which is even, lets say,
so what we get is a positive value.

Therefore, a negative base with even power is always a positive value.
