Giana Rios · Answer 1

the value of f (1) is smaller than the value of f (3)

Step-by-step explanation:

If you fill in f (1) you get

f (1) = -2 * 1^2+3*1+10

f (1) = -2 * 1+3+10 = 15

If you fill in f (3) you get

f (3) = -2 * 3^2+3*3+10

f (3) = -2 * 9+9+10 = 27.

So f (1) = 15 and f (3) = 27. Since 27 is bigger than 15, f (3) is bigger than f (1).
