The function is:
f ( x ) = 1,000 · 2^x
x is the number of weeks.
1. y - intercept is : y = 1,000.
2. The y-intercept represents the cicada population at the start ( for x = 0 ).
f ( 0 ) = 1,000 · 2^0 = 1,000 · 1 = 1,000.
3. The 2 in the function shows that cicada population doubles every week.
Answer: =9x^6−9
Step-by-step explanation:
Let's simplify step-by-step.
−18/2+9x^6
=−9+9x^6
The slope is 0.
Using the formula (y2-y1) / (x2-x1), we wee that when subtracting y2 from y1 we get zero in the numerator and 7 in the denominator.
0/7 = 0
Another way to determine this is by plotting the two points and seeing that they form a horizontal line, indicating that there is a slope of 0.
Answer:
the question isnt clear
Step-by-step explanation:
Well, we know that the two consecutive numbers have to be negative, because if it was positive, the smaller number multiplied by two would be much greater. (unless 1 and 2). So, by guessing and checking, we will get -13 and -14 :)
