Answer:
We can have two cases.
A quadratic function where the leading coefficient is larger than zero, in this case the arms of the graph will open up, and it will continue forever, so the maximum in this case is infinite.
A quadratic function where the leading coefficient is negative. In this case the arms of the graph will open down, then the maximum of the quadratic function coincides with the vertex of the function.
Where for a generic function:
y(x) = a*x^2 + b*x + c
The vertex is at:
x = -a/2b
and the maximum value is:
y(-a/2b)
Answer:
K
Step-by-step explanation:
As per diagram, the intersection of the line JL and plane R is the point K
Correct option is the last one
Answer:
$8
Step-by-step explanation:
To find 10% of a number, move the decimal point over by one. Since the number is a whole the decimal point looks like this
$40.00
Move it once to get 10% which is 4. Then multiply it by 2 to get 20%.
