Let f (x)=1/x and g (x)=x^2+5x. A. Find (f×g)(x). B. Find the domain and range of (f×g)(x).
Ira Lisetskai [31]

we are given

f(x)=\frac{1}{x}

g(x)=x^2+5x

(A)

(f×g)(x)=f(x)*g(x)

now, we can plug it

(fXg)(x)=\frac{1}{x} (x^2+5x)

we can simplify it

(fXg)(x)=\frac{1}{x} (x(x+5))

(fXg)(x)=x+5

(B)

Domain:

Firstly, we will find domain  of f(x) , g(x) and (fxg)(x)

and then we can find common domain

Domain of f(x):

f(x)=\frac{1}{x}

we know that f(x) is undefined at x=0

so, domain will be

(-\infty,0)∪(0,\infty)

Domain of g(x):

g(x)=x^2+5x

Since, it is polynomial

so, it is defined for all real values of x

now, we can find common domain

so, domain will be

(-\infty,0)∪(0,\infty)..............Answer

Range:

Firstly, we will find range of f(x) , g(x) and (fxg)(x)

and then we can find common range

Range of f(x):

f(x)=\frac{1}{x}

we know that range is all possible values of y for which x is defined

since, horizontal asymptote will be at y=0

so, range is

(-\infty,0)∪(0,\infty)

Range of g(x):

g(x)=x^2+5x

Since, it is quadratic equation

so, its range will be

[-6.25,\infty)

now, we can find common range

so, range will be

(-6.25,0)∪(0,\infty).............Answer

What is 2 3/5 + 1 3/5
Vlada [557]

Answer: 4 1/5


Step-by-step explanation:

Rewriting our equation with parts separated


=2 + 3/5 + 1 + 3/5


Solving the whole number parts


2 + 1= 3


Solving the fraction parts


3/5 + 3/5 = 6/5


Simplifying the fraction part, 6/5,


6/5 = 1 1/5


Combining the whole and fraction parts


3 + 1+ 1/5 = 4 1/5


Solution by Formulas


converting mixed numbers to fractions, our initial equation becomes,


13/5 + 8/5


Applying the fractions formula for addition,


=(13 × 5) + (8 × 5)/5 × 5


=65+40 / 25


=105/25


Simplifying 105/25, the answer is


=4 1/5
