Answer:

3x²+8x-35

Step-by-step explanation:

<u>FOIL stands for:</u>

First -> (3x-7)(x+5)

Outer -> (3x-7)(x+5)

Inner -> (3x-7)(x+5)

Last -> (3x-7)(x+5)

Following FOIL, we get:

(3x-7)(x+5)

(3x)(x)+(3x)(5)+(-7)(x)+(-7)(5)

3x²+15x-7x-35

3x²+8x-35

Therefore, the expanded form is 3x²+8x-35

Realtions??? IDK someone please explain
Greeley [361]
A relation is what it sounds like. A relation between numbers and/or objects.

A function is just a special type of relationship. In order for a relation to be a function, it must have only one output for one input.

On a graph, the x-axis is the input and the y-axis is the output. If you draw a vertical line through a point on the x-axis and there is only one point on that vertical line, then it is a function.

The only graph that meets these criteria is the first graph.
