Is y=2x-1 a function?

Mathematics
1 answer:
nignag [31]3 years ago
4 0

Answer:

It is a function.

Step-by-step explanation:

By definition, a function relates each element in the domain to only one element in the range. This means that each vertical line you draw through the x-axis can intersect the function at only one point. ... y = 2x +1. This is the equation of a straight line with slope 2 and y-intercept 1, so it is a function.

A linear function is two distinct but related notions. So, y=2x-1 is also a linear function.

Is number 3 is correct and please help with number 4
adoni [48]
No, you forgot to multiply by 5 ml.

250/250 * 5 = 5 ml by mouth three times a day

#4 has to be in correct units. you cannot divide grams by milligrams.

I would change dose to milligrams 0.1g * 1000 = 100 mg dose. Quantity is 1 capsule

100/100 * 1 = 1 pill by mouth twice daily
