? is this real

2. hawkfalcon

Yeah. Ikr:(

3. hawkfalcon

$f(x) = x^3 - 2x; [0,4]$

4. anonymous

average rate of change in (a,b) is: f(b)-f(a)/b-a

5. anonymous

rate of change = $\frac{f(4) - f(0)}{4 - 0} = \frac{4^3 - 2\times4 - \left( 0 - 0 \right)}{4} = \frac{64 - 8}{4} = 14$

O.o I like how they give us work which they haven't taught us. Thank you:)
