Answer:

f(x) = x² - 9x + 18

General Formulas and Concepts:

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Binomial Roots: (x + a)(x + b)(x + c)(x + ...)
  • Expanding by FOIL-ing (First, Outside, Inside, Last)

Step-by-step explanation:

<u>Step 1: Define</u>

Zeros/Roots x = 3, 6

<u>Step 2: Find Function</u>

  1. Rewrite Binomial Roots:                    f(x) = (x - 3)(x - 6)
  2. Expand by FOIL-ing:                          f(x) = x² - 6x - 3x + 18
  3. Combine like terms (x):                      f(x) = x² - 9x + 18

What value of x is in the solution set of 3(x-4)greater than or equal to 5x+2
Gnesinka [82]

3(x-4)>= 5x+2

Distributing 3 on x-4

3(x)-3(4)>=5x+2

3x-12>=5x+2

Now we need to move x terms together and the numbers together and for that we subtract 5x to both sides and add 12 to both sides

-2x >=14

Now we need to get rid of -2, and for that we divide both sides by -2 and on dividing by negative number, the sign of inequality change , that is

x<=-7

Evaluate................
wolverine [178]

Answer:

h(8q²-2q) = 56q² -10q

k(2q²+3q) = 16q² +31q

Step-by-step explanation:

1. Replace x in the function definition with the function's argument, then simplify.

h(x) = 7x +4q

h(8q² -2q) = 7(8q² -2q) +4q = 56q² -14q +4q = 56q² -10q

__

2. Same as the first problem.

k(x) = 8x +7q

k(2q² +3q) = 8(2q² +3q) +7q = 16q² +24q +7q = 16q² +31q

_____

Comment on the problem

In each case, the function definition says the function is not a function of q; it is only a function of x. It is h(x), not h(x, q). Thus the "q" in the function definition should be considered to be a literal not to be affected by any value x may have. It could be considered another way to write z, for example. In that case, the function would evaluate to ...

h(8q² -2q) = 56q² -14q +4z

and replacing q with some value (say, 2) would give 196+4z, a value that still has z as a separate entity.

In short, I believe the offered answers are misleading with respect to how you would treat function definitions in the real world.
