Which functions meet the necessary criteria for the extreme value theorem? Check all that apply.

f(x) = over [–5, 5]
f(x) = over [–4, 2]
f(x) = 4x2 + 7x – 1 over [1, 8]
f(x) = tan(x) over [0,]
f(x) = –9x3 + 8 over [–10, 10]
f(x) = over [–6, 4]

Step-by-step explanation:

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
