F(x) = — 3х2 – 6х +5 <br> maximum and minimum value
gregori [183]

9514 1404 393

Answer:

  maximum: 8; no minimum

Step-by-step explanation:

A graph can be useful. I find a graphing calculator handy. It shows the maximum of the function is f(-1) = 8. Since the parabola goes to -∞ for large values of x, there is no minimum.

  maximum: 8

__

You can also find the maximum by putting the function in vertex form.

  -3(x^2 +2x) +5 . . . . factor the leading coefficient from the x terms

 -3(x^2 +2x +1) +5 -(-3)(1) . . . . add the square of half the x-coefficient, subtract the equivalent amount

  -3(x +1)^2 +8 . . . . . . the vertex form of the expression for f(x)

This form is ...

  a(x -h)^2 +k . . . . . with a=-3, h=-1, k=8

so the vertex is (h, k) = (-1, 8) -- the same as shown on the graph. The negative value of 'a' tells you the parabola opens downward, so the vertex is the maximum. The maximum is 8 at x = -1.

Nataly [62]

A plastic skeleton is

Answer: B. a physical model.

The world has lots of different kinds of models. A mathematical model might be a ball travels according to the equation y = v_0 t - \frac 1 2 gt^2. This isn't that. A computer model would be a program that somehow simulates a skeleton in the computer, this isn't that either. Our skeleton is an actual physical model just like a model airplane.
