Determine if the following relations represent y as a function of x.
lana [24]
<h3>Answers:</h3>
  • A) No, it is not a function
  • B) Yes it's a function
  • C) Not a function
  • D) Yes it's a function
  • E) Yes it's a function

================================================

Explanation:

If y has an exponent of 2, 4, 6, etc (basically any even number) then it leads to having inputs with multiple outputs.

Consider something like y^2 = x. If x = 100, then y = 10 or y = -10 are possible. A function can only have exactly one y output for any valid x input. Similar issues happen for things like y^4 = x and so on. So this is why A and C are not functions.

The other equations do not have y values with such exponents, so we can solve for y and have each x input lead to exactly one y output. Therefore, they are functions.

I think u guys know what to do !!!
kotykmax [81]

Answer:

B, C

Step-by-step explanation:

7 - x = 18

A.

7 - 2x = 18 - x

126 - 14x = 324 - 18x

We are nowhere near the solution.

B.

-x = 11

x = -11

This works.

C.

7 = x + 18

-11 = x

This works.

D.

25 - x = 36

-25 + x = -36

This does not help.

E.

7 = x + 18

0 = x + 11

We still do not have a solution.

Answer: B, C

What is the solution of
loris [4]

Answer:

x = -1/2

Step-by-step explanation:

1-3x = x+3

Add 3x to each side

1-3x+3x = x+3x+3

1 = 4x+3

Subtract 3 from each side

1-3 = 4x+3-3

-2 = 4x

Divide each side by 4

-2/4 = 4x/4

-1/2 =x
