A botanist collected data on the growth of sunflowers to maturity. She modeled the equation y = x + 1 2 for the line of best fit. The independent variable, x, is time in weeks and the dependent variable, y, is height in feet. What does the slope mean in this context? A) The sunflower's starting height is 1 foot.
B) The sunflower's starting height is 1 2 feet.
C) The sunflower's height increases by an additional 1 foot each week.
D) The sunflower's height increases by an additional 1 2 foot each week.

The answer is C

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

replication and blocking

step-by-step explanation:

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
