Which function is not defined at 0? Select one: O a. f(x) = ex Ob. f( x) = 7 X O c. f( x) = 1x/ O d. f ( x) =Vx O e. f(x) = sin x Of. f( x) =x3 O g. f(x) = x2 Oh. f ( x ) = 1 1+ex Oi. f( x) = xWhich function is bound below, but not above? This means that a horizontal line can be drawn below the graph that it will never touch. Select all that apply. Select one or more: O a. f(x) =x3 O b. f( x) = log x O c. f ( x ) = - 1 1 te - x O d. f( x) = \\x De. f ( x ) = 1 X Of. f(x) = sin x O g. f ( x) = Vx Oh. f(x) = ex Oi. f( x ) =x2 Oj. f( x) =xHow would you compare the maximum and minimum values of the functions f(x) = x2 and f(x) = x3? Select one: O a. The function f(x) = x2 has a maximum value while f(x) = x3 has a minimum value. O b. The function f(x) = x2 has a minimum value while f(x) = x3 has a maximum value. O c. The function f(x) = x2 has a maximum value while f(x) = > does not have a maximum value. O d. The function f(x) = > has a minimum value while f(x) = x does not have a minimum value. Explain why the function f(x) = v x is not defined for all values of x. Select one: O a. The square root of a fraction is not a real number. O b. The square root of a decimal is not a real number. O c. The square root of any negative number is not a real number. O d. The square root of 0 is not a real number
