If g(x) = 3x + 2 and h(x) = 9x2 + 12x + 6, find a function f such that f ○ g = h
Virty [35]
F(g(x)) = f(3x+2) = h(x)=9x^2+12x + 6

Note that (3x+2)^2 = 9x^2 + 12x + 4, which is almost, but not quite, equal to h(x).

Let's experiment.  What if f(x) = x^2 + 2?

Then f(3x+2) = (3x+2)^2 + 2 = 9x^2 + 12x + 4 + 2 = 9x^2 + 12x + 6, which is the same as the given h(x).

Thus, f(x) is x^2 + 2.

Answer:

  • x +3x = 180
  • x = 45 . . . . . . . choice C
  • 3x = 135 . . . . . choice F

Step-by-step explanation:

Let x represent the measure of the original angle in degrees. Three times its measure is 3x. That will be the supplement if the sum of the two angles is 180°.

  x + 3x = 180 . . . . . . . . . equation for finding the angle

  x = 180/4 = 45 . . . . . .  divide both sides by 4

  3x = 3(45) = 135

The first angle is 45°. The second angle is 135°.
