Answer:
Step-by-step explanation:
11 degrees. 13 + -2 = 11. The starting temperature was 11 degrees farenheit
max is at vertex
in form 
the x value of the vertex is 
given, 
a=6, b=0
the x value of the vertex is -0/(2*6)=0
the y value is 
so vertex is at (0,-1)
since the value of a is positive, the parabola opens up and the vertex is a minimum value of the function
therefore that value is the smallest value the function can be
domain=numbesr you can use for x
range=numbesr you get out of inputting the domain
domain=all real numbers
range is {y | y≥-1} since y=-1 is the minimum
Round up to 1, 400 then times it by 5
1,400 • 5 = 7,000
So no, it it's not reasonable.
I'M soo not sure on this one. But if I did the math correctly your answer would be C. 64
Hoped I help!
Also sorry if its wrong.
