But if it’s only to the cards it should be 50% out of 50%

Given f(x)=3x2−5x−2 .<br><br> What is the value of f(−23) ?

Sonja [21]

$f(x) = {3x}^{2} - 5x - 2 \\ f( - 23) = ... \\ f( - 23) \: means \: x = - 23 \\ so \: f( - 23) = {3( - 23)}^{2} - 5( - 23) - 2 \\ = 3(529) + 115 - 2 \\ = 1700$

If x > 0 then |x|/x = 1 !!!

If x<0 then |x|/x = -1

*below is an explanation! :)

_______________________________________

- I found the answer to this by choosing a any number that satisfies the requirement of x > 0 and plugging it into |x|/x

-----

Watch this!

Let's take 10 for example. 10 is greater than 0 like x>0 requires!

Let's plug it into |x|/x

|10| ÷ 10 = 1

*Remember that | | this means "absolute value" or whatever is in between the two bars will always be positive (+)

-------

Now let's take a random number that satisfies 0> x and do the same as we did above!

Let's take -3 and plut it into |x|/x

|-3| ÷ -3 = -1
