Determine whether the relation represents a function. If it is a function, state the domain and range. {(-3, 7), (2, 5), (5, -3), (8, -2)}

(a) The relation is a function

(b)

Step-by-step explanation:

Given

(a): Is it a function?

A relation has the form:

For the relation to be a function, all the x values must be unique and not repeated.

In , the x values are: -3, 2, 5 and 8.

None of the values are repeated.

Hence, the relation is a function

(b): The domain and the range:

The x values represent the domain while the range are represented by the y values.

So, we have:

what's that

5x+2x=49

7x=49

x=7. 35 apples
