x | y
0 | 0 = (5*0)³
1 | 125 = (5*1)³
2 | 1000 = (5*2)³
3 | 3375 = (5*3)³
The function is not linear (or straight) because the variable x is raised to the power of 3, that is:
[tex]f(x)=(5x)^3=5^3x^3=125x^3[/tex]
Then, the function is cubic.
The function is not exponential because the variable x is not in the exponent of any expression.
