If f(x) = - 2x2 + 2x - 3, what is f(5)?

Mathematics
1 answer:
Ghella [55]3 years ago
3 0

Answer:

f(5)= - 43

Step-by-step explanation:

<u>Numerical Value of Functions </u>

A function can be seen as an equation that has only one value of y for every x inputted. It assigns exactly one output to every input value. Our function is defined by

f(x)=- 2x^2 + 2x - 3

To find f(5) we only need to replace the value of x into the given expression.

f(5)=- 2(5)^2 + 2(5) - 3

f(5)=- 2(25) + 10 - 3

f(5)=- 50 + 10 - 3

\boxed{f(5)=- 43}

victus00 [196]
<span>$100.00 rounded  value
$105.00 rounded value
$110.00 rounded value

For example,
14,494 </span>
<span>To round off the height value to the nearest thousand we can use the expanded from to clarity the position of numbers which is: </span>
<span>10, 000 = ten thousand </span>
<span>4, 000 = thousands </span>
<span>400 = hundreds </span>
<span>90 = tens </span>
<span>4 = ones </span>
<span>Here we can notice than four thousand is the value where the nearest thousands is placed. Hence we can round off the number of 14, 494 into 14, 000. Notice 0-4 rounding off rules.<span>
