Which of the following is a valid comparison between the possible minimum and maximum values of the function y = -x2 + 4x - 8 an

Arturiano [62]

Answer:

The maximum value of the equation is 1 less than the maximum value of the graph

Step-by-step explanation:

We have the equation $y=-x^2+4x-8$ .

We can know that this graph will have a maximum value as this is a negative parabola.

In order to find the maximum value, we can use the equation $x=\frac{-b}{2a}$

In our given equation:

a=-1

b=4

c=-8

Now we can plug in these values to the equation

$x=\frac{-4}{-2} \\\\x=2$

Now we can plug the x value where the maximum occurs to find the max value of the equation

$y=-(2)^2+4(2)-8\\\\y=-4+8-8\\\\y=-4$

This means that the maximum of this equation is -4.

The maximum of the graph is shown to be -3

This means that the maximum value of the equation is 1 less than the maximum value of the graph

inessss [21]

Answer: 8 bagels for 5

Step-by-step explanation:so you’re going to divide the price to the quantity which will be 5/8= 0.6

3.39/6=0.56 ans you’ll take the 8 bagels for 5 because one bagel is approximately like the 6 bagels for 3.39
