Tasya [4]
David's age: x
Joshua: x + 5
Simon: (x+5) + 4 or x + 9

Simon's age + David's age = 15
(x+9) + (x) = 15
2x = 15 - 9
2x/2 = 6/2
x = 3

The ages of the boys:

David: x = 3 years old
Joshua: 3+5 = 8 years old
Simon: 3+9 = 12 years old

Use the graph of the polynomial function to find the factored form of the
Anarel [89]

The factored form of the related polynomial is (x - 1)(x - 9)

<h3>How to determine the factored form of the related polynomial?</h3>

In this question, the given parameter is the attached graph

From the graph, we can see that the curve crosses the x-axis at two different points

These points are the zeros of the polynomial function.

From the graph, the points are

x = 1 and x = 9

Set these points to 0

x - 1 = 0 and x - 9 = 0

Multiply the above equations

(x - 1)(x - 9) = 0

Remove the equation

(x - 1)(x - 9)

Hence, the factored form of the related polynomial is (x - 1)(x - 9)

PLEASE HELP WITH THESE LIMITS ASAP!
marusya05 [52]

Answer:

  • 4
  • -4

Step-by-step explanation:

When you follow the curve from the left toward x=2, you wind up at the open circle at (2, 4). The limit from that direction is 4.

When you follow the curve from the right toward x=2, you wind up at the open circle at (2, -4). The limit from that direction is -4.

\lim\limits_{x \to 2^-}{f(x)} =4\\\\\lim\limits_{x \to 2^+}{f(x)} =-4
