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

Alexeev081 [22]
X, X+2, X+4 ARE THE 3 POSITIVE CONSECUTIVE INTEGERS.
X(X+2)=8+38(X+4)
X^2+2X=8+38X+152
X^2+2X-38X-8-152=0
X^2-36X-160=0
(X-40)(X+4)=0


X-40=0
X=40 ANSWER FOR THE FIRST INTEGER.
40+2=42 FOR THE SECOND INTEGER.
