If f(x) = -5-4 and g(x) = -3 -2 find (f-g)(x)

asambeis [7]

Answer:

The correct answer option is D. $-5^x+3x-2$

Step-by-step-explanation:

We are given the following two functions:

$f(x)=-5^x-4$

and

$g(x)= -3x-2$

We are to find $(f-g)(x)$ so we will subtract the function g from function f, arrange the like terms together and combine them like shown below to get:

$(f-g)(x) =(-5^x-4)-(-3x-2)$

$(f-g)(x)=-5^x-4+3x+2$

$(f-g)(x)=-5^x+3x-2$

Therefore, $(f-g)(x)$ is equal to $-5^x+3x-2$ so the correct answer option is D. $-5^x+3x-2$ .

Solve the equation 4b + 22 = 5(b + 4) − 1

djverab [1.8K]

4b + 22 = 5 (b + 4) - 1 (remove the parantheses)

4b + 22 = 5b + 20 - 1 (calculate)

4b + 22 = 5b + 19 (move the terms)

4b - 5b = 19 - 22 (collect like terms and calculate)

-b = -3 (change the signs)

b = 3

What is the inverse of the function f(x) = 4x + 8?

Viktor [21]

Answer: FIRST OPTION.

Step-by-step explanation:

Given the following function:

$f(x)= 4x + 8$

Follow this steps in order to find its inverse:

1. Rewrite the function with $y=f(x)$ :

$y= 4x + 8$

2. Solve for "x":

$y-8= 4x\\\\x=\frac{y-8}{4}\\\\x=\frac{y}{4}-2$

3. Now you must exchange the variables:

$y=\frac{x}{4}-2$

4. And finally, rewrite the function with $h(x)=y$ :

$h(x)=\frac{x}{4}-2$

Therefore, the inverse function is $h(x)=\frac{x}{4}-2$
