F(3) for f (x) =1/2(4)^x

Tomtit [17]

Answer:

Step-by-step explanation:

f(x) = 1/2(4)^x

Plug in 3 for x

f(3) = 1/2(4)³

Cube 4.

4³ = 4 x 4 x 4 = 64

f(3) = 1/2(64)

Multiply 64 with 1/2 (or divide by 2)

f(3) = 64/2

f(3) = 32

What are the points of inflection of k(x)=sinx-(1/4)sin2x

zalisa [80]

Answer:

Option d is correct.

Step-by-step explanation:

The point of inflection of a function y = f(x) at a pointy c is given by f''(c) = 0.

Now, the given function is

$k(x) = \sin x - \frac{1}{4}\sin 2x$

Differentiating with respect to x on both sides we get,

$k'(x) = \cos x - \frac{1}{2} \cos 2x$

Again, differentiating with respect to x on both sides we get,

$k''(x) = - \sin x + \sin 2x = - \sin x + 2 \sin x \cos x$

So, the condition for point of inflection at point c is

k''(c) = 0 = - sin c + 2 sin c cos c

⇒ sin c(2cos c - 1) = 0

⇒ sin c = 0 or $\cos c = \frac{1}{2}$

⇒ c = 0 or $c = \pm \frac{\pi}{3}$

Therefore, option d is correct. (Answer)
