Answer 11

5. Given no other restrictions, what are the domain and range of the following function?

f(x) = x^2 - 2x + 2

Answer 12

well, the domain is all the values that x can take. the range is all the values of f(x) for those values of x. what is your answer?

Answer 13

are there any values that x can't be?

Answer 14

im confused. I'm sorry

Answer 15

Okay, a function is a relationship, a little machine that takes numbers as input and produces other numbers. Are there any numbers that won't fit into this machine? I can't think of any. 0 works, negative numbers all work, positive numbers all work...so the domain is all numbers, right?

Answer 16

finding the range is a bit trickier. we have to characterize the sorts of output we can get from that machine.

Answer 17

What do you get if you plug 0 in for x?
