Which statement is true of the function f(x) = -3/? Select three options.
The function is always increasing.
The function has a domain of all real numbers.
The function has a range of {y|- The function is a reflection of y = 3.
The function passes through the point (3,-27).

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
