Weba) Is X and Y the same thing? as it refers to the question whether x and y are equal. A singular item. However it is taught in school that both X and Y are already 2 items; therefore the subjects need to be referred in a plural. Furthermore the result is singular item. Hence. C) Are X and Y the same thing? WebOct 29, 2007 · An extremum occurs at certain points where f' is zero. As the name suggests, a maximum (or minimum), is the greatest (or lowest) value that the function takes within a specific interval. Therefore it refers to f (x) (or y, if you prefer), where f' (x) = 0. Where this value occurs...that's at x. Last edited: Oct 29, 2007.
Are linear regression and least squares regression necessarily the same …
WebYou do exactly the same thing in either case: you plug in –1 for x, multiply by 2, and then add the 3, simplifying to get a final value of +1. But function notation gives you greater … WebY is just defining a variable. Variables can be thought of as just a label for an unknown value. A lot of times you see variables defined as an expression involving another variable (e.g. y … how old was stevie nicks in fleetwood mac

WebMay 11, 2024 · "X and Y are not the same: foo is X but not Y, and bar is Y but not X" is just such a common rhetorical device! A minor tweak of the wording might leave a clearer impression of what you actually mean. $\endgroup$ – Silverfish. May 12, 2024 at 13:25. 1 $\begingroup$ Yeah, I agree with @Silverfish. This is the best answer in my opinion. WebQuestion 173374: is f(x)*g(x) the same as f(g(x)) ? Answer by Mathtut(3670) (Show Source): You can put this solution on YOUR website! we need functions if f(x)=x+1 and g(x)=2x+5 then f(x)*g(x)= (x+1)(2x+5)= : whereas f(g(x))=f(2x+5)=(2x+5)+1=2x+6.....: so in this case no they do not equal each other:if f(x)=x and g(x)=y: f(x)*g(x)=xy and f(g(x ... WebJun 14, 2016 · No. They have no special significance. Explanation: All of these are simply used by convention to refer to a function. For example, f (x) = ex, a(x) = ex, and z(x) = ex all mean the same thing. However, some notations mean only one thing. For example, ζ(s) refers to the Riemann zeta function: ∞ ∑ n=1 1 ns merion in the welsh tract
