Answer:

$(f-g)(x)$

$f(x)-g(x)$

$x^{2} -6x-27-x+9$

$x^{2} -7x-18$

----------------------

$(f*g)(x)$

$=f(x)g(x)$

$(x^{2} -6x-27)(x-9)$

$=x^{3} -15x^{2}+27x+243$

----------------------

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

$\frac{x^{2} -6x-27}{x-9}$

$\frac{(x-9)(x+3)}{x-9}$

$x+3$

-----------------------

$(f+g)(x)$

$f(x)+g(x)$

$=x^{2} -6x-27+x-9$

$=x^{2} -5x-36$

Solve the equation. Identify any extraneous solutions

Lelu [443]

Squaring both sides of the given equation: w^2=7w, or w^2-7w=0.

w^2-7w=0 can be factored: w(w-7)=0. Then, w=7 or w=0. Both 0 and 7 are solutions of this equation.

A function, f(x)=4x+5, has a domain 0<=x<=50. What is the range? How do you do this??

babunello [35]

Step-by-step explanation:

remember the domain is the interval or set of valid input (x) values. the range is the interval or set of the valid result (y) values.

so, the given domain tells us the interval to look at.

what are the functional values of the function between 0 and 50 ?

since the function is continuous (there are no gaps) in this interval, we can safely assume that all values between f(0) and f(50) are valid y values.

f(0) = 4×0 + 5 = 5

f(50) = 4×50 + 5 = 205

so, the range is 5 <= y <= 205
