Can there be functions in which the domain and range do not intersect at all? Yes. For example, the functionf(x)=−1√xf(x)=−1xhas the set of all positive real numbers as its domain but the set of all negative real numbers as its range. As a more extreme example, a function...

What are the domain and range of the function y= 2\sqrt{3x + 4} - 5? What function has a domain of all real numbers? Which function has a domain of all real numbers? What are the domain and range of the function y = 2 square root {3 x + 4 - 5}?
Domain: All real numbers Range: y ≥ 1 Identify the domain and range of y = x² + 2x + 5. Domain: All real numbers Range: y ≥ 4 Identify the domain and range of y = -x² + 6x - 11. Domain: All real numbers Range: y ≤ -2 Identify the domain and range of y = -x...
How can we identify a range that isn't all real numbers? Like the domain, we have two choices. We can look at the graph visually (like the sine wave above) and see what the function is doing, then determine the range, or we can consider it from an algebraic point of view. Variable...
The domain and range are the set of all real numbers. The graph is obtained by reflecting in the x-axis that part of the parabola y = x2,站酷海洛,一站式正版视觉内容平台,站酷旗下品牌.授权内容包含正版商业图片、艺术插画、矢量、视频、音乐素材、字体等,已先后
(i) f(x)=-|x|,x∈RWe know that |x|=\(x_1+x_2≥0-x_1fx0.∴f(x)=-|x|=\(-a,ifx≥0x,ffx0Since f(x) is defined for x∈R , the domain of f is RIt can be observed that the range of f(x)=-|x| is all real numbers except positive real numbers.∴ The range of ...
Find the Domain and Range e^x${\displaystyle {e}^{x}}$ 答案 The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.Interval Notation:${\displaystyle (-\infty ,\infty )}$Set-...
