If ` f:I ->N` then the function ` f(x)` cannot be 1) one-one 2) onto 3) both 1 and 2 4) None of these

Show that the function f(x)=3x+ 2 is one-one and onto

Show that the function f(x)=3x+2 is one-one and onto.

Show that the function f(x)=3x+2 is one one and onto

Let the function f: R-{-b}->R-{1} be defined by f(x)=(x+a)/(x+b) , a!=b , then f is one-one but not onto (b) f is onto but not one-one (c) f is both one-one and onto (d) none of these

Let the function f: R-{-b}->R-{1} be defined by f(x)=(x+a)/(x+b) , a!=b , then (a) f is one-one but not onto (b) f is onto but not one-one (c) f is both one-one and onto (d) none of these

Let f : R^+ ->{-1, 0, 1} defined by f(x) = sgn(x-x^4 + x^7-x^8-1) where sgn denotes signum function then f(x) is (1) many- one and onto (2) many-one and into (3) one-one and onto (4) one- one and into

Let f : R^+ ->{-1, 0, 1} defined by f(x) = sgn(x-x^4 + x^7-x^8-1) where sgn denotes signum function then f(x) is (1) many- one and onto (2) many-one and into (3) one-one and onto (4) one- one and into
