Well you can see that it must be a linear function as the highest degree is 1, only x. So now, it says f(-1/2), which means that x=-1/2. Substitute -1/2 for x. -3+4(-1/2)= -3+-2=-5.
Easy?

Dude, this is the second time a similar question has been asked.
f(anything) = sub "anything" into the equation and solve. Can't remember exactly how you show that the equation is linear. I'm guessing you're not into calculus so those methods will not work. The exponent on the "x" is 1, therefore it's a linear function.

Yes, it is linear. You can tell it is linear because the highest degree of the equation is 1. f(x) = -5.
