Question

amelia is documenting the height of sunflower plants each week. she has determined the function to be f(x) = 3x 3, 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? domain, nonnegative values; range, values greater than or equal to 3 domain, nonnegative values; range, values greater than −1 domain, nonnegative values; range, values less than −1 domain, nonnegative values; range, values less than or equal to 3

Answer 1

When you graph this it is -7 which So it's c

Answer 2

The correct option is 1.

Explanation:

The given function is

`f(x)=3x+3`

where, x represents time and f(x) represents the height of the plant.

Domain is the set of input values x and range is the set of output values y.

Domain is non negative values because the value of time can not be negative.

Minimum value of x could be 0. Substitute x=0 in the given function.

`f(0)=3(0)+3=0+3=3`

The minimum value of f(x) is 3 at x=0. The value of function increases as x increases. So, range are the values greater than or equal to 3.

Therefore the correct option is 1.
