Y+100=x^2 graph the following equation

Slope-intercept form is the easiest to help visualize graphs so you would isolate the y making it y = x^2 - 100. It is now clear to see that this is the parent graph of y=x^2 shifted down 100 units.

What is the answer to this and why?
Anna007 [38]

Answer:

Step-by-step explanation

I get the same answer you do, but I'm not at all certain I'm correct. I would have done it just as you did letting each y value define the new x value and then putting the - on the left in at the very end.

f(1) = 3

f(3) = -1

f(-1) = 7

But there is a minus in front of the left most f. That would make it - 7

A 2-column table with 8 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2, 3, 4. The
IceJOKER [234]

Answer:

Step-by-step explanation:

So I'm going to  make the table here.

x     f(x)

-3     -2

-2     0

-1     2

0     2

1     0

2     -8

3     -10

4     -20

Without looking at the answers we are going to deduce what intervals could make f(x) positive.  Well, where  is it shown as positive for the numbers given?  well f(-1) and f(0) are positive, both at 2.  then both f(-2) and f(1) are 0, then everything below -2 and above 1 make f(x) negative, so it looks like everything up until -2 is negative, but increasing then at -2 it turns to 0 and keeps increasing  at least until some time after f(-1).  It might even just stay at 2 until it gets to f(0), and then after that it decreases.  Hopefully that makes sense.

Given the description, and if you on't understand I can try to explain more carefully, where does it look like it's positive?  Well, it goes from negative to 0 at -2, then after that it's positive until 1, where it turns to 0 again, before decreasing.    so everything between -2 and 1 look to make f(x) positive.  Since f(-2) and f(1) don't themselves though it means they are not included, so you use parenthesis.

so the answer is (-2,1)  Again, let me know if you need more of an explanation.

3x(4x^4-5x) simplify the expression
mrs_skeptik [129]

Answer:

\boxed{\bold{12x^5-15x^2}}

Explanation:

Apply Distributive Law

= \bold{3x\cdot \:4x^4-3x\cdot \:5x}

= \bold{3\cdot \:4x^4x-3\cdot \:5xx}

Simplify \bold{3\cdot \:4x^4x-3\cdot \:5xx: \ 12x^5-15x^2}

= \bold{12x^5-15x^2}

Mordancy.
