Hi there!

$f(x)+f(x+1)=4f(x)$

There are 3 parts to this equation:

f(x)

f(x+1)

4f(x)

We must first determine these three parts separately.

1) f(x)

We're given that $f(x)=3^x$ :

⇒ $f(x)=3^x$ :

2) f(x+1)

Now, we must find f(x+1). To do so, add 1 to x in the original function $f(x)=3^x$ :

⇒ $f(x+1)=3^x^+^1$

3) 4f(x)

To find 4f(x), multiply the original function $f(x)=3^x$ by 4:

$4f(x)=4*3^x$ :

4) Put it all together

Now, plug each of the three parts into the equation $f(x)+f(x+1)=4f(x)$ :

$f(x)+f(x+1)=4f(x)$

$3^x+3^x^+^1=4*3^x\\3^x+3^x*3=4*3^x$

Factor the left side

$3^x*(1+3)=4*3^x$

Divide both sides by 3^x

$1+3=4\\4=4$

Because this equation is true, $f(x)+f(x+1)=4f(x)$ is therefore true.

I hope this helps!

Help 1000 points i will give you more this question is hard

AlexFokin [52]

Answer:

H) 2

Step-by-step explanation:

$\frac {\sqrt {1 - \cos^{2}x}}{\sin x} + \frac {\sqrt {1 - \sin^{2}x}}{\cos x}$

= $\frac {\sin x}{\sin x} + \frac {\cos x}{\cos x}$ [since 0 < x < (π/2) and $\sin^{2}x + \cos^{2}x = 1$ ]

= (1 + 1)

= 2

We know that in general,

by $\sqrt {x}$ we mean the positive square root of x only.

Write in slope-intercept form an equation of the line that passes through the given points. (-1, -1) (1, 5)

PSYCHO15rus [73]

<h2>Answer:</h2>

Step 1: We need to find the slope (or m) FIRST using slope formula*.

$m = \frac{5 - (-1)}{1 - (-1)}\\\\m = \frac{6}{2} = 3$

m = 3

Step 2: Now we find the y-intercept (or b) using the slope-intercept formula**, ONE of the 2 points given, and the slope we just found.

$5 = 3(1) + b\\\\5 = 3 + b\\\\2 = b$

b = 2

Step 3: Now we put it all together we get our equation in slope-intercept form**.

$y = 3x + 2$

**Slope-intercept form: $y = mx + b$

*Slope formula: $m = \frac{y_2 - y_1}{x_2 - x_1}$
