Answer:

Yes, it is a function

Step-by-step explanation:

A function has only one output for each input. So a function can have the same output for different input, but one input can only have one output. In this case none of the inputs output more than one output, so it is a function.

The difference of two numbers if four and their product is 60
cricket20 [7]

Answer:

The two numbers are 10 and 6.

Step-by-step explanation:

Let's begin by calling these two numbers x and y, and setting up a system of equations.

x-y=4

x*y=60

Now, you can rearrange the first equation to find the value of x expressed through y.

x=y+4

Now, you can substitute this into the second equation.

(y+4)*y=60

y^2+4y=60

y^2+4y-60=0

(y-6)(y+10)=0

y=6

x=6+4=10

Hope this helps!
