Answer:
Step-by-step explanation:
The coefficient of x² is is a negative 0.6, so this function has a maximum value.
the max value of a quadratic function is the value of f(x) when x=-b/2a,
in this case, a=-0.6, b=382
so x=382/1.2=
r(382/1.2)=-0.6(382/1.2)²+382*(382/1.2)
use a calculator: 60801.67 is the number I got.
Answer: x=90
Step-by-step explanation:
because the range is 8, and the highest value in the data set is 98, x must equal 96
On your X-axis, go to -5 and identify which Y-coordinate it is. For this problem, it would be -2.
45=9*5=3*15
clearly, none of these factors have a sum of 3 considering a negative factor
