This problem says to write the product of the sum and the difference. (x+5)(x-5). I'm not sure what my teacher is asking me to do.

Step-by-step explanation:

step 1. x + 5 and x - 5 are polynomials.

step 2. x + 5 is a sum, x - 5 is a difference.

step 3. (x + 5)(x - 5) is a product which means to multiply. So "multiply" using FOIL.

step 4. (x + 5)(x - 5) = x^2 - 5x + 5x- 25 = x^2 - 25.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
