Explain: how would you model 5 x 2/3
ELEN [110]
Well as you can see 5 x 2/3= 3 1/3 there is 7 steps to figure it out

1. set up the problem
5 x 2/3

2. put a 1 on 5 to make it a fraction
5/1 x 2/3

3. multiply and divide
(5 x 2) / (1/3)

4. find out the answer
10/3

5. turn the answer into a mixed fraction
10 divided by 3= 3.1 3 stays the same you don't need to say 1

6. it equals
3 1/3

7. so the answer is
3 1/3

The graph of f(x) = x2 is translated to form g(x) = (x – 5)2 + 1. On a coordinate plane, a parabola, labeled f of x, opens up. I
Firdavs [7]

The <em>quadratic</em> function g(x) = (x - 5)² + 1 passes through the points (2, 10) and (8, 10) and has a vertex at (5, 1).

<h3>How to analyze quadratic equations</h3>

In this question we have a graph of a <em>quadratic</em> equation translated to another place of a <em>Cartesian</em> plane, whose form coincides with the <em>vertex</em> form of the equation of the parabola, whose form is:

g(x) = C · (x - h)² - k     (1)

Where:

  • (h, k) - Vertex coordinates
  • C - Vertex constant

By direct comparison we notice that (h, k) = (5, 1) and C = 1. Now we proceed to check if the points (x, y) = (2, 10) and (x, y) = (8, 10) belong to the parabola.

x = 2

g(2) = (2 - 5)² + 1

g(2) = 10

x = 8

g(8) = (8 - 5)² + 1

g(8) = 10

The <em>quadratic</em> function g(x) = (x - 5)² + 1 passes through the points (2, 10) and (8, 10) and has a vertex at (5, 1).
