Prove, using the second derivative, that the general quadratic y= ax^2+bx+c, is:
lozanna [386]

There are three things you have to know:

  • A function is convex when its second derivative f''(x)>0
  • A function is concave when it second derivative f''(x)
  • The derivative of a power, x^n, is nx^{n-1}

So, the first derivative is

y'=2ax+b

and the second derivative is

y''=2a

This implies that the second derivative of a parabola is constant, and of course that 2 doesn't change the sign of a.

Lee earned some money from a summer job he saved 1/4 of the money and spent 1/3 of the rest on a t-shirt he then spent the remai
Marat540 [252]
They need to be like terms (so change the denominators into things that match)
<u>1 </u>x3 = <u>3</u>
4 x3 = 12

<u>1 </u>x4 = <u>4</u>
3 x4 = 12

4/12 + 3/12 = 7/12 

So, 7/12 of the money was spent.

50 PTS Identify the parent function that can be used to graph the function f(x)=(1/4x)^3
Kobotan [32]

Answer:

f(x) = x^3

Step-by-step explanation:

f(x) = (1/4x )^3

y = f(Cx)  

y = x^3  and C = 1/4

This function is stretched in the x direction

The parent function is x^3

Use the graph below to fill in the blank with the correct number:
n200080 [17]
Can you attach the graph? 

But what you have to do is do find -2 on your graph and see the point there. Since f(-2) needs to have -2 in the x of the point, the (-3,0) and (1,0) dont matter. So check your graph for the points (-2, 2) and (-2, 1). Whatever point on your graph matches, then thats the answer
