Is (3,7), (3,8), (3,9), (3,10) a function

Answer:

(3,7), (3,8), (3,9), (3,10) is not a function.

Step-by-step explanation:

A function is defined as a relation in which each input value has only a single output value.

This means that for each x value there should be only one y  

value. If this criteria is not fulfilled then the relation cannot be called a function.

For the given set of points, we notice that for x=3, y=7,8,9,10 which shows there are many y-values o for a single x-value. This means there are many outputs for a single input. This disqualifies it to be a function.

Thus, (3,7), (3,8), (3,9), (3,10) is not a function.

Please help! Create a set of five positive numbers (repeats allowed) that have a median of 10 and a mean of 14. What thought pro
Brilliant_brown [7]
Alright, since there are 5 numbers, and the mean (or average) is (sum)/(amount of numbers), we have (sum)/5=14. Multiplying both sides by 5, we have the sum being 80. The median of 10 means that in a, b, c, d, e, 10 has to be c and the numbers have to be in ascending order. A and b must be 10 or lower, while d and e must be 10 or higher. Putting some random numbers in, we can have 1, 1, 10, 15, and e. We left e there because the sum needs to be 80, and since 1+1+10+15=27, 80-27=53=e. This, however, would not work if e was less than 10 and we therefore would have needed to make some numbers lower to compensate for this. Our answer is therefore 1, 1, 10, 15, 53

If f(x) = 5x(3exponent) - 2 and g(x) = 2x+1 , find (f+g) (x)
Rus_ich [418]

For this case we must find

(f + g) (x).

By definition we have to:

(f + g) (x) = f (x) + g (x)

We have the following functions:

f (x) = 5x ^ 3-2\\g (x) = 2x + 1

Now, applying the given definition, we have:

(f + g) (x) = 5x ^ 3-2 + 2x + 1\\(f + g) (x) = 5x ^ 3 + 2x-1

Answer:

(f + g) (x) = 5x ^ 3 + 2x-1

What is the converse of the following conditional statement? If x = –10, then x2 = 100
tangare [24]
The converse would be If x² = 100 then x = -10

So essentially if the conditional statement is p → q then the converse is q → p (In essence, the converse of a conditional statement  is formed by interchanging the hypothesis and the conclusion.)
