The function y = –3(x – 2)2 + 6 shows the daily profit (in hundreds of dollars) of a hot dog stand, where x is the price of a hot dog (in dollars). find and interpret the zeros of this tion a. zeros at x = 2 and x = 6 b. zeros at c. the zeros are the hot dog prices that give $0.00 profit (no profit). d. the zeros are the hot dog prices at which they sell 0 hot dogs.

Ответ:
the serose of the x value is where y=0,
that is where profit=0
the zeroes of the y value is where x=0
that's when the price is 0 dollars
ok
x zeroes
solve for when y=0
x zeroes at and
y zeroes
x=0
the y zeroes are where they sell 0 hot dogs for 0 dollars, it is $-6 profit
the x zereoes are where you make 0 profit, that occurs when you sell and hot dogs
not sure which answer you want because it doesn't specify which zeroes we want
A is wrong tho
Ответ:
y = (3/2)x + 11
Step-by-step explanation:
We can start from the point slope form of a linear function:
(y-y1)=m(x-x1)
The slope m can be determined from the points given as m = (y2-y1)/(x2-x1)=(8-2)/(-2-(-6))=6/4=3/2
Then use either of the given points as x1, y1 to complete the equation (I picked the point (-6,2):
y-2=(3/2)(x+6)
You can rearrange this to:
y = (3/2)x + 11
