2x^2 + 2x - 24

= 2x^2 + 8x - 6x -24

= 2x(x + 4) -6(x + 4)

= (x+4)(2x-6)

Answer:

.

Step-by-step explanation:

The trick here is to notice that all 3 terms can be div. by 2:

2(x^2 + x - 12)

Note that -12 factors into -3 * 4 or -4 * 3.  Thus,

x^2 + x - 12 = (x-4)(x+3), and so 2x2 + 2x − 24 = 2(x-4)(x+3).

What trigonometric function represents the graph? (6 points)
Alja [10]
<span>The correct option is: A. f(x) = 4sin(x − π/2), because:
</span>
 1. When you evaluate x=π/2 in the function f(x) = 4sin(x − π/<span>2), you obtain:
</span>
 f(π/2) = 4sin(π/2− π/2)
 f(π/2) = 4sin(0)
 f(π/2) = 4(0)
 f(π/2) = 0 (As you can see in the graphic)

 2. If you evaluate x=π in the same function, then you have:

 f(π) = 4sin(π− π/2)
 f(π) = 4sin(π/2)
 f(π) = 4 (As it is shown in the graphic)
