Vertex of the quadratic equation is the highest or the lowest point of the quadratic equation.

<h3>Given-</h3>

The given equation in the question is,

f(x) = x^2 - x +2

<h3>Vertex of the quadratic equation</h3>

Vertex of the quadratic equation is the highest or the lowest point of the quadratic equation.

To find the vertex of the equation we need to compare the given equation with the following equation.

f(x)=a(x-h)^2+k

Here h and k are the vertex of the equation.

The given equation is,

f(x) = x^2 - x +2

Rewrite the equation,

f(x) = x^2 - x +(\dfrac{1}2)^2} +2-(\dfrac{1}2)^2}

f(x) = x^2 - x +\dfrac{1}{4} +2-\dfrac{1}4}

f(x) =(x-\dfrac{1}{2} )(x-\dfrac{1}{2} )+2-\dfrac{1}{4}

f(x) =(x-\dfrac{1}{2} )^2+\dfrac{7}{4}

Thus the vertex of the quadratic equation is 1/2 and 7/4.

For f(x)=2x+1 and g(x)=x^2-7, find (f+g)(x)
labwork [276]

For this case we have the following functions:

f (x) = 2x + 1\\g (x) = x ^ 2-7

We must find the following sum of functions:

(f + g) (x)

By definition we have to:

(f + g) (x) = f (x) + g (x)\\(f + g) (x) = 2x + 1 + x ^ 2-7\\(f + g) (x) = x ^ 2 + 2x-6

So, we have to:

(f + g) (x) = x ^ 2 + 2x-6

Answer:

(f + g) (x) = x ^ 2 + 2x-6

Using linear function concepts, it is found that:

a) The initial value is of 3 and the rate of change is of 20.

b) The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and also can be considered as the initial value.

In this problem, the function that gives the charge C for renting a bicycle for h hours is:

C(h) = 3h + 20

Item a:

Comparing to the standard function, we have that:

  • The initial value is of 3 and the rate of change is of 20.

Item b:

The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.
