Can someone PLEASE tell me if I'm right?
Gregor is documenting the height of pea plants each week. He has determined the function to be f(x) = 2x + 1, where x represents time and f(x) represents the height of the plant. Which of the following options describes the restrictions to the domain (x) and range f(x) correctly?
A. Domain, nonnegative values; range, values greater than −0.5
B. Domain, nonnegative values; range, values less than −0.5
C. Domain, nonnegative values; range, values greater than 1
D. Domain, nonnegative values; range, nonnegative values
Is it D?

Best ResponseYou've already chosen the best response.1Hint* can the plant ever be smaller than 1? *Knowing that the domain is greater than or equal to 0 that is*

Best ResponseYou've already chosen the best response.0the domain and range are all nonnegative values?

Best ResponseYou've already chosen the best response.1Not quite Since the domain we know is always greater than or equal to 0 The smallest 'x' we can plug in is 0...and if we do that we get y = 1 So with the SMALLEST domain value, we would have a result of 1 This means we can never have a range *within this domain* than includes a number LESS than 1 So it would look as though C is correct here
