To find f(-20), first figure out which piece x = -20 fits with.

Since -20 < -12, x = -20 first in the domain used by the third piece.

For f(-20), treat this function as if it was just f(x) = 3x-7.

f(-20) = 3(-20) -7

         = -60 - 7

         = -67

Use the given facts about the functions to find the indicated limit.
oksian1 [2.3K]

Answer: Option b.

Step-by-step explanation:

 1. You can rewrite it as following:

\lim_{x\to \ -6} 2

This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 2, no matter the value of x.

\lim_{x\to \ -6} 2=2

 \lim_{x\to \ -6} 1

 This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 1, no matter the value of x.

\lim_{x\to \ -6} 1=1

2. Then:

\lim_{x\to \ -6} (f/g)(x)=2/1=2

3. The answer 2.

How do I factor x^4-5x^2+6?
Vilka [71]

Answer:

=(x^2-3)(x^2-2)

Step-by-step explanation:

So we have the expression:

x^4-5x^2+6

And we wish to factor it.

First, let's make a substitution. Let's let u be equal to x². Therefore, our expression is now:

=u^2-5u+6

This is a technique called quadratic u-substitution. Now, we can factor in this form.

We can use the numbers -3 and -2. So:

=u^2-2u-3u+6

For the first two terms, factor out a u.

For the last two terms, factor out a -3. So:

=u(u-2)-3(u-2)

Grouping:

=(u-3)(u-2)

Now, substitute back the x² for u:

=(x^2-3)(x^2-2)

And this is the simplest form.

And we're done!

F(x)
Ludmilka [50]
F(x) = 5 + 2x  where x is the number of times he walks the neighbours dog
y-intercept is at y=5 and slope = 2

g(x) :-  As x increases by 4 g(x) decreases by -8  so the slope is -8/4 =  -2
when x = 0, g(x)  = the y intercept  is at -1 + (-8/2) = - 5
so equation of g(x) is  g(x) = -5 -2x
h(x):-    the slope is  (3 - 5) / (1 - 0)      [  difference in y values / diff in x values]
slope = -2
so we have h(x) = -2x + c   where c = the y-intercept
when x = 0  h(x) = 5
so  c = 5
 h(x) = 5 - 2x   

  Now j(x)= 2x - 5   - slope is 2 and y intercept = -5
