**12+ Sketch The Graph Of The Function. F(X) = 3 + X If X < −2 X2 If −2 ≤ X < 2 6 − X If X ≥ 2
Pics**. We'll follow these suggested steps information from f '': F(x)=⎧⎪⎨⎪⎩3−5x if x≤33x if 3<x<7 5x+1 if x≥7.

If the second derivative is positive, then concave up. Prove that the equation cos x = x3 has a real root. Computing the derivative and setting it to 0 we nd 2x − 2 = 0 =⇒ x = 1.

### To find #f(0)#, we have to examine, where in the defn.

Let f ∈ ca, b and n between a and b. I am pretty good at graphing piecewise functions and considering each condition one by one and graphing it, but this one is really confusing me, i the graph has a positive slope from when x = 1 to when x = 3. This problem has been solved! There is no simpler function that initial function is obtained from.
