Let f(x)=9-x^2, g(x)=3-x. Find (f-g)(x) and its domain

Lynna [10]

Answer:

$(f-g)(x)=-x^2+x+6$

Domain:

$(-\infty,\infty)$

Step-by-step explanation:

we are given

$f(x)=9-x^2$

$g(x)=3-x$

Calculation of (f-g)(x):

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

we can plug it

$(f-g)(x)=9-x^2-(3-x)$

now, we can simplify it

$(f-g)(x)=9-x^2-3+x$

$(f-g)(x)=6-x^2+x$

$(f-g)(x)=-x^2+x+6$

Domain:

we know that

domain is all possible values of x for which any function is defined

and f(x),g(x) and (f-g)(x) are polynomials

so, domain will be all real numbers

so, we get

$(-\infty,\infty)$

Measure of a verticle angle is 7x+182 and another angle is 9x+194 solve for x

disa [49]

The measures of 2 vertical angles are always equal, so we have:

7x+182=9x+192.

Rearranging, we have 182-192=9x-7x, which simplifies to -12=2x.

Thus, x=-6.

This means that the angles are:

i) 7x+182=7(-6)+182=182-42= 140(degrees).

ii) 9x+194=9(-6)+194=194-54=140 (degrees, as expected.)

Answer: x=-6
