Write the quadratic function in standard form.<br> f(x) = -x2 + 2x + 4<br> f(x) =
goldenfox [79]

Answer:

f(x)=-1(x-2)^2+8

Step-by-step explanation:

Given:

The quadratic function is given as:

f(x)=-x^2+2x+4

The standard form of a quadratic function is given as:

f(x)=a(x-h)^2+k, where, 'a', 'h' and 'k' are real numbers.

Now, in order to convert the given function to standard form, we use completing by  square method.

-x^2+2x=-(x^2-2x)=-[(x-2)^2-2^2]=-[(x-2)^2-4]=-(x-2)^2+4

Now, f(x)=-x^2+2x+4 can be rewritten as:

f(x)=-(x-2)^2+4+4\\f(x)=-1(x-2)^2+8

Therefore, the standard form of the function is:

f(x)=-1(x-2)^2+8

How do you find the average rate of change of a function over an interval?
Kaylis [27]
Average rate of change over an interval =

(difference in value of the function between the
beginning and end of the interval)
       divided by
(length of the interval).

Example:

If the function was 200 pounds at the beginning, and 98 pounds 3 hours later,
then the average rate of change is  (98 - 200) / 3 = -34 pounds per hour.

Express as a trinomial. (x - 4)(2x - 5)
vladimir2022 [97]

Answer:

\boxed{ \bold{  \huge{ \boxed{ \sf{2 {x}^{2}  - 13x + 20}}}}}

Step-by-step explanation:

\sf{(x - 4)(2x - 5)}

Use the distributive property to multiply each term of the first binomial by each term of the second binomial

⇒\sf{x(2x - 5) - 4(2x - 5)}

⇒\sf{2 {x}^{2}  - 5x - 8x + 20}

Collect like terms

⇒\sf{2 {x}^{2}  - 13x + 20}

Hope I helped!

Best regards!!
