Given the equation $y=a{x}^3+7,$

which of the following, if any, are correct $C$ statements for this equation?

a$)y=a**x**x**x+7$

b$)y=a^{**}x**x**(x+7)$;

c$)y=(a^{**}x{)}^{**}x**(x+7)$;

d$)y=(a**x)**x**x+7$;

e$)y=a**(x**x**x)+7$

f$)y=a**x**(x**x+7)$

Check the output for each case, then decide. $($Show your decision in output statement$)$
