A function f is defined by `f(x)" "=" "2x" "" "5` . Write down the values of (i) `f(0)` , (ii) `f(7)` , (iii) `f(3)` .

Text Solution

Verified by Experts

The correct Answer is:
N/a
Function f (x) =2x -5
(i) `f(0)=2.(0)-5=-5impliesf(0)=-5`
(ii) `f(7)=2.(7)-5=14-5=9impliesf(7)=9`
(iii) `f(-3)=2.(-3)-5=-6-5=-11impliesf(-3)=-11.`
