 2. 
State whether the given equation or function is linear. Write yes or no. Explain your reasoning.
f(x) = 9x3 + 5
a.
Yes, the equation is linear. It is of the form f(x) = m + b
b.
Yes, the equation is linear form. It is of the form f(x) = mx + b.
c.
No, the equation is not linear. It is not of the form f(x) = mx + b.
d.
No, the equation is not linear. It is in the form x + y = c.
 

 3.
