Which is f(5) for the function â€""2x2 2x â€"" 3? â€""107 â€""63 â€""43 â€""37.
artcher [175]
<h3>Answer:</h3>

Option B: 63

<h2>Given that:</h2>

The given function is    f(x)=2x^2+2x+3

<h2>Explanation:</h2>

To evaluate the value of a function at given value of input, you should replace the variable given in the function with the value of input that is given, in your case it is x = 5.

For x = 5, we have

f(5) = 50 + 10 + 3      = 63

Similarly, you will be able to evaluate the value of the function for any other input given, which is assumed to be valid.

Hence option b: 63 is the correct option.

− 3/4 is a rational number, but not an integer. Explain why below.
Rus_ich [418]
A rational number is any number that can be expressed as a fraction. An integer is a whole number. -3/4 is a fraction but not a whole number, so it is rational but not an integer.

Brandon bought a pair of sneakers for $55 that had a regular price of $90. Find the percent of change.
Rudiy27

Answer:

63.6% (rounded to nearest tenth)

Step-by-step explanation:

To find the percent change, you need to find the change first. So subtract 55 from 90 and you get 35. Then you divide 35 and 55 to get the percent change (you also need to multiply that answer to get the percent.)
