let x = the price of a book
so you would have
total = 3x-20
Answer:
<u>Non linear</u>, because x is squared. It's a bi-quadratic polynomial, not a linear polynomial.
Answer:
Step-by-step explanation:
(2-4x)+(2-4x)+(-2x+8)=12-10x
The probability should be 1/60
Answer:
f(x)=x-5 is a linear function
Step-by-step explanation:
so there are no restrictions to what x can be. The domain is all real numbers. In interval notation, we show that is can be anything from negative infinity through infinity like this: This says that the lower limit of the domain is negative infinity and the upper limit is positive infinity.
