Can E X 2 Be Negative It is never negative and its expectation which also can t be negative is equal to E X E X E E X which is not hard to show using linearity of expectation E2 x E 2 x
We could observe that operatorname Var X E X 2 E X 2 and that the variance is always nonnegative However since it isn t that hard to show it might be nice to Can f x be negative Clearly not and it s easy to see if we rewrite the relation as f x f x 2 2 For all x f x is the square of some real number and so it must be

The Taylor expansion of e x 1 x x 2 2 x 3 6 x 4 24 If x is negative then we expect e 1000 for example to be very close to 0 however using the first 5 terms above we I understand that the sign shows the order of magnitude if its positive or negative but what about the number behind the sign It starts with a zero So is the zero ignored or is
So the answer is such A function needs to have a y for each x and for negative numbers this is only true when x is an integer NOTE If you re working with complex numbers then this Therefore as our practical case of exponential functions shows an exponential function cannot have a base of 0 1 or a negative value How do you know if its a exponential

Your teacher probably said that exp x 2 or exp x 2 does not have an antiderivative that can be expressed using elementary functions In mathematics an elementary function is a Another problem we run into as we deal with negative bases is that some negative values raised to certain exponent powers may result in complex values that cannot be graphed
Dividing is the inverse opposite of Multiplying A negative exponent means how many times to divide by the number Example 8 1 1 8 1 8 0 125 Or many divides Example 5 3 1 You can t have a base that s negative For example y 2 x isn t an equation you have to worry about graphing in pre calculus If you re asked to graph y 2 x don t fret You read this as
