Answer:

The relation is <u>not</u> a function.

Step-by-step explanation:

A function is a relation in which no two ordered pairs have the same input and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input corresponds with <u><em>exactly</em></u> one output.

In this case, the answer is no. The input value of 10 corresponds with two output values, 4 and 20. It only takes one input value to associate with more than one output value to be <u>invalid</u> as a function.

Therefore, the given relation is <em><u>not</u></em> a function.

Which number is prime? 36 37 35 38

dybincka [34]

A number is prime if its only divisors are 1 and the number itself.

Out of your numbers, 36 and 38 are even, and thus divisible by 2, so they aren't prime.

Similarly, 35 ends with 5, so it's divisible by 5, and is not prime.

37 is divisible only by 1 and 37, and thus it's prime.

Y= − 2 ( x − 2 ) ( x + 8 ) −2(x−2)(x+8) in standard form

Harlamova29_29 [7]

Answer:

$y=-4x^{2} -24x+64$

Step-by-step explanation:

$y=-2(x-2)(x+8)-2(x-2)(x+8)$

$y=-2x^{2} +12x+32-2(x-2)(x+8)$

$y=-2x^{2} -12x+32-2x^{2} -12x+32$

$y=-4x^{2} -24x+64$
