WebYes - that is how it works, if you have f (x)=x² and are asked what is f (2), then you replace every instance of x in the function definition with 2 so given f (x) = x², that means f (2) = 2² = 4. Here is another example: If f (x) = x² + 5x then f (2) = 2² + (5) (2) = 4 + 10 = 14 1 comment ( 12 votes) Upvote Downvote Flag more Show more...
Determining whether values are in domain of function
WebMar 30, 2024 · The function f (x) = √x is not defined for negative values of x. Therefore, the domain of f (x) is the set of non-negative real numbers (x ≥ 0). In other words, the function f (x) can only be applied to non-negative real numbers, and it does not make sense to talk about the value of f (x) for negative values of x. WebApr 6, 2024 · In every function where the denominator is zero there is an undefinition. Another example: f (x)= square root of x, in this case the function is defined for zero and every positive value of "x", we can not work out a square root of negative numbers, at least … gwrych castle hotel

WebIt is defined at x=1, because h(1)=2 (no "hole") But at x=1 you can't say what the limit is, because there are two competing answers: "2" from the left, and "1" from the right; so in fact the limit does not exist at x=1 (there is a "jump") And so the function is not continuous. WebMath Suppose f: R → R is defined by the property that f (x) = x cos (x) for every real number x, and g: R → R has the property that (gof) (x) = x for every real number . Then g' (π/2) =.
