a) The number of elements in the range of a constant function

b) If $f\left(x\right)=a{x}^5+b{x}^3+cx+d$  is an odd function, then the value of  d is

c) If $\text{f:R} \to \text{R}$ defined by$f\left(x\right)\text{=3}x–\text{4}$ , then $f^{–\text{1}}\text{(5)=}$

d) If $f:R^{+}\to R$  such that$f\left(x\right)\text{=log5}x$ , then $f^{–\text{1}}\text{(-1)=}$

Then  arrange the above values in ascending order
