Graph the function f(x) = − x4 + 7x3 − 9x2 − 3x + 10 using graphing technology and identify for which values of x the graph is d

jolli1 [7]

In the attached diagram you can see the graph of the function $f(x) = -x^4 + 7x^3 - 9x^2 - 3x + 10.$

As you can see graph is:

1. increasing from x = −2 to x = −1

2. decreasing from x = 0 to x = 1

3. decreasing and then increasing from x=1 to x=2

4. increasing from x=2 to x=4.

Answer: correct choice is B.

Answer: 1. ∠A= 80.75° 2. 41.79 $cm^2$

Step-by-step explanation:

Since, According to the sines low,

$\frac{sin A}{CB} = \frac{sin C}{AB}$

Here, CB= 4.1 cm, AB = 3.3 and ∠ C = 52.6°

$\frac{sin A}{4.1} = \frac{sin 52.6}{3.3}$

⇒ $sin A = 4.1\times\frac{sin 52.6}{3.3}$

⇒ $sin A =0.98699998308$

⇒ A = 80.75°

2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1

=34.86 + 6.93

= 41.79 square cm
