3.84 meters because 2% of 48 is 0.96, 0.96*4, which is 3.84
259% increase because 6 x 2 is 12 and 3 is the remainder and 3/6 is 50%
You used to say "y = 2x + 3; solve<span> for y when x = –1". Now you say "f(x) = 2x + 3; find f(–1)" (pronounced as "f-of-x is 2x plus three; find f-of-negative-one"). You do exactly the same thing in either case: you plug in –1 for x, multiply by 2, and then add the 3, simplifying to get a final value of +1.
