F(x) = 4x + 4 g(x) = 3x +7

salantis [7]

Answer:

Part 1) $(f+g)(x)=7x+11$

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

Part 3) $(f/g)(x)=\frac{(4x+4)}{(3x+7)}$

Part 4) In interval notation the domain is (-∞,-7/3) ∪ (-7/3,∞)

Part 5) $(f o g) (x)=12x+32$

Step-by-step explanation:

we have

$f(x)=4x+4$

$g(x)=3x+7$

Part 1) Find (f+g)(x)

we know that

$(f+g)(x)=f(x)+g(x)$

substitute the given functions

$(f+g)(x)=(4x+4)+(3x+7)$

Combine like terms

$(f+g)(x)=7x+11$

Part 2) Find (f-g)(x)

we know that

$(f-g)(x)=f(x)-g(x)$

substitute the given functions

$(f-g)(x)=(4x+4)-(3x+7)$

$(f-g)(x)=4x+4-3x-7$

Combine like terms

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

Part 3) Find (f/g)(x)

we know that

$(f/g)(x)=\frac{f(x)}{g(x)}$

substitute the given functions

$(f/g)(x)=\frac{(4x+4)}{(3x+7)}$

Part 4) What the domain for the answer in question 3

we have

$(f/g)(x)=\frac{(4x+4)}{(3x+7)}$

we know that

The denominator of the quotient cannot be equal to zero

$3x+7=0$

$3x=-7$

$x=-\frac{7}{3}$

The domain is all real numbers except the number x=-7/3

In interval notation the domain is (-∞,-7/3) ∪ (-7/3,∞)

Part 5) Find (f o g) (x)

we know that

$(f o g) (x)=f(g(x))$

substitute

$f(g(x))=4(3x+7)+4$

$f(g(x))=12x+28+4$

$f(g(x))=12x+32$

therefore

$(f o g) (x)=12x+32$

What makes 50.652 rational?

Ivanshal [37]

Remember a rational number is a number that can be written with two whole numbers in a fraction, for example, 0.25 can be written as 1/4 notice how, both, the numerator and denominator are whole numbers AKA Integers(numbers that aren't decimals or fractions).

any number that can't be written by whole numbers in the numerator or denominator is an irrational number, things like Pi, Pi cannot be written by two whole numbers in the fraction.

50.652, is definitely rational because the fraction does not need decimal numbers in the numerator or denominator.

it can be written as:
$50 \frac{50}{50}$ or $\frac{12663}{250}$

notice how neither the numerator or denominators are decimals?
