Question

find the range of f(x) = 2x + 0.1 + 0.01.

Answer 1

First, combine like terms
f(x)=2x+.11
because it is a linear equation, the range is all real numbers

Answer 2

Thanks! I have another one. Find the domain of f(x0 = 52x + 1 -4.
I think the domain is all real numbers.

Answer 3

f(x) = 52x + 1 -4

Answer 4

Yes, anytime it is a linear equation, it is always all real numbers for domain and range (since it extends both ways) unless it is a flat horizontal line (then it is all real numbers for domain, and the y-value will be the range) and if it is a vertical line, then it is not a function
