Which expression both gives the average rate of change of the function h(x)

liubo4ka [24]

Answer:

Step-by-step explanation:

The average rate of change of a function over an interval a ≤ x ≤ b is found by:

$\frac{f(b)-f(a)}{b-a}$

Here, a is 0 and b is 3, so: $\frac{f(3)-f(0)}{3-0}=\frac{f(3)-f(0)}{3}$

Just plug in 3 for the first term and 0 for the second term in the numerator:

- First term: $\frac{1}{2} (3^{3+\frac{1}{2} })+3=\frac{1}{2} (3^{3\frac{1}{2} })+3$

- Second term: $\frac{1}{2} (3^{0+\frac{1}{2} })+3=\frac{1}{2} (3^{\frac{1}{2} })+3$

So, the final answer is:

$\frac{[\frac{1}{2} (3^{3\frac{1}{2} })+3]-[\frac{1}{2} (3^{\frac{1}{2} })+3]}{3}$

Thus, the answer is D.

Hope this helps!

Answer:

y = - $\frac{7}{2}$ cos ( $\frac{1}{2}$ x ) , y = cos ( 3x ) + 2

Step-by-step explanation:

Image 1.

The graph is reflection of cosine over x-axis and max is 3.5 ⇒ A = - $\frac{7}{2}$

Period is ( 4 π ) ⇒ B = $\frac{1}{2}$

There are no horizontal and vertical shifts ⇒ C = D = 0

y = -  $\frac{7}{2}$  cos (  $\frac{1}{2}$  x )

Image 3.

The graph of cosine shifted 2 units up only ⇒ D = 2 , C = 0

Period of the given function is $\frac{2\pi }{3}$ ⇒ B = 3

y = cos ( 3x ) + 2
