Use the function f(x) = x2 − 2x 8 and the graph of g(x) to determine the difference between the maximum value of g(x) and the mi
slamgirl [31]

The difference between the maximum value of g(x) and the minimum value of f(x) is 5.

Given function is:

f(x)=x^{2} -2x+8......(1)

<h3>What is the general form of a quadratic equation?</h3>

The general form of a quadratic equation is ax^{2} +bx+c=0 with a\neq 0.

As we know the minimum value of a quadratic function is \frac{4ac-b^{2} }{4a} when a>0

For f(x) a>0 so minimum value of f(x) = \frac{4*1*8-(-2)^2}{4*1}=7

From the graph, the maximum value of g(x) =12

So, the difference between the maximum value of g(x) and the minimum value of f(x) =12-7 =5

Hence, the difference between the maximum value of g(x) and the minimum value of f(x) is 5.

Write a system of linear equations that has the ordered pair (1,4) as it's solition
Lemur [1.5K]

The required system of equations is x+y=5\\x-y=-3

Step-by-step explanation:

We need to write a system of linear equations that has the ordered pair (1,4) as it's solution.

It means we need to find  system of linear equations, which after being solved gives x=1 and y=4

Let the system of equations be:

x+y=5\\x-y=-3

I have made equations such that adding x+y gives 5 i,e (1+4=5) and subtracting x-y gives -3 (1-4=-3)

Now solving this system of equations to find value of x:

x+y=5\,\,eq(1)\\x-y=-3\,\,eq(2)

Adding eq(1) and eq(2)

x+y=5\\x-y=-3\\-----\\2x=2\\x=1

Putting value of x=1 into eq(1) to find value of y

x+y=5\\1+y=5\\y=5-1\\y=4

The solution set after solving system of equations is (1,4).

The required system of equations is x+y=5\\x-y=-3
