If f(x) = x^2-1 which of the following ordered pairs would be on the graph of f(x)

Mathematics

Alex Ar [27]3 years ago
6 0

These following ordered pairs are on the graph:

  • (0,1)
  • (5, 24)
  • (-2,3)

-------------------------------

An ordered pair (x, f(x)) will be on the graph if replacing them into the equation, we get an equivalence.

-------------------------------

The equation is:

f(x) = x^2 - 1

-------------------------------

(0,1)

Here, we test x = 0, f(x) = 1

Replacing into the equation:

1 = 0^2 - 1

1 = -1

False, so not on the graph.

-------------------------------

(0,1)

Here, we test x = 1, f(x) = 0

Replacing into the equation:

0 = 1^2 - 1

0 = 0

True, so on the graph.

-------------------------------

(3,5)

Here, we test x = 3, f(x) = 5

Replacing into the equation:

5 = 3^2 - 1

5 = 8

False, so not on the graph.

-------------------------------

(5,24)

Here, we test x = 5, f(x) = 24

Replacing into the equation:

24 = 5^2 - 1

24 = 24

True, so on the graph.

-------------------------------

(-2,3)

Here, we test x = -2, f(x) = 3

Replacing into the equation:

3 = (-2)^2 - 1

3 = 3

True, so on the graph.

-------------------------------

(-4,-17)

Here, we test x = -4, f(x) = -17

Replacing into the equation:

-17 = (-4)^2 - 1

-17 = 15

False, so not on the graph.

Your problem statement makes no reference to p or q, so we can only guess that "p/q" refers to the ratio of the lowest- and highest-degree coefficients:

... -6/1

Then the factors of p/q are the factors of 6, with either sign.

Factors of p/q: ±1, ±2, ±3.

There are a number of ways the factors can be tested. To test 1, simply add the coefficients. (The sum is -8.) To test -1, subtract the sum of odd-degree coefficients from the sum of even-degree coefficients. (The difference is 0.)

Knowing that -1 is a root of the function, you can use synthetic division to find the quadratic factor. (See the first attachment for the work.) Then you have ...

... f(x) = (x +1)(x² +x -6)

You can continue to test the factors of p/q, or you can factor the quadratic to get ...

... f(x) = (x +1)(x -2)(x +3)

Another way to test the factors is to program your graphing calculator to evaluate the function f(x) for those factors. The result from my TI-84 is shown in the second attachment. That shows f(x) = 0 for x = -3, -1, and +2.

Test the factors: f({-3, -2, -1, 1, 2, 3}) = {0, 4, 0, -8, 0, 24}

This tells you the x-intercepts.

X-intercepts: -3, -1, 2

Of course, the y-intercept is just the constant in the function—the value of the function when x=0.

Y-intercept: -6

As with any odd-degree polynomial with a positive leading coefficient, the overall behavior looks like "/". That is ...

End behaviors: f(x) goes to -∞ as x goes to -∞; f(x) goes to +∞ as x goes to +∞.

_____

A graph of f(x) is shown in the third attachment. (Graphing calculators make it easy to use graphing to find x-intercepts.)

If a cylender has a volume of 340ft and a radius of three ft what is the height
rewona [7]

Answer:

h = 12.03

Substitute 22÷7 for pi.

h = V ÷ πr²

h = 340 ÷ (22÷7) × 3²

   ≈ 12.03
