Given the function f(x)=-5x^2+2x+9,find f(1) and f(2) Choose the statement that is true concerning these two values

6 0

F(1) = -5(1)^2+2(1)+9 = 6
f(2) = -5(2)^2+2(2)+9 = -9

So, because f(1) = 6 is positive and f(2) = -9 is negative, f(1) > f(2).

f(1) is greater than f(2)!

Kruka [31]

So 0.5 ft per day is the same as 0.5 ft per 24 hours. This equals 0.5/24 ft an hour. 0.5 ft /24=0,02083 ft. Simple conversion yields 0.02083*12=0.25. So the vine can grow by .25 inches per hour.
