If f(x) = (x + 3)(x − 3), complete the square and determine the minimum or maximum value of the function.

Mathematics

Westkost [7]2 years ago

Answer:

Minimum of -9

Step-by-step explanation:

f(x) = (x + 3)(x − 3)

Distribute:

f(x) = x² − 9

In vertex form:

f(x) = 1 (x − 0)² − 9

The leading coefficient is positive, so this is an upwards parabola, meaning the vertex is a minimum.  The vertex is at (0, -9).  So the minimum of the function is -9.

According to the fundamental theorem of algebra, which polynomial function has exactly 6 roots? f (x) = 5 x superscript 4 baseli
MariettaO [177]

The polynomial with 6 roots is the one of degree 6, so the correct option is:

f(x) = 7x^6 + 3x^2 + 12

<h3>Which polynomial function has 6 roots?</h3>

You need to remember that if p(x) is a polynomial of degree N, then it has N roots (such that some of these N roots may be equal or not).

Then we just need to find the polynomial of degree 6. (Remember that the degree represents the maximum exponent of the polynomial).

In this case, the only one of degree 6 is:

f(x) = 7x^6 + 3x^2 + 12

Which is the last option.

For the standard normal curve, find the z-score that corresponds to the 30th percentile. -0.47 -0.98 -0.53 -0.12
Nata [24]
We are looking for the Zo score that corresponds to the 30th percentile.
 We use the table for the standard normal distribution.
 From P (Z <Zo) = 0.3 we search for Zo.
 Then we look in the table for the value of Zo that corresponds to 0.3.
 Hence, the approximate value is -0.53.
 The option is the third

Please help me I would also like an explanation
Tasya [4]

Answer:

k = 45*

2k = 90*

Step-by-step explanation:

K will be the same as the 45* degrees, as it is across from it.

2k is twice k, which is 90*.

45* + 45* + 90* = 180*

Good luck!
