There are few features that you can use to sketch any polynomial function

First is to find x-intercepts of that polynomial. x-intercepts are positions x axis at which function f(x) is equal to 0

Second feature is to find first derivative of the function f(x), make it equal to 0 and again find x values that make first derivative equal to 0. after that implement those x values in f(x) to find f(x) for those values. Now you have sets of (x,y)  which are local minimum and maximums of polynomail. Knowing these and with a bit of calculation you can  make a decent skecth of any polynomial.

You can also set x=0 to find y- intercept.

Hi!

The combination of 4 digit numbers using those numbers are: 3, 276; 3, 762; 3, 267; 3, 726; 3, 672 etc. This is pretty easy, now you try.

Hope I helped! Have a nice day!

WHAT ARE THE EXCLUDED VALUES?
hichkok12 [17]
Since the denominator cannot be zero, you can set 4z+1=0 to find the excluded values. 
4z+1=0
4z=-1
z=-1/4
And thus, z cannot equal -1/4

Find the value of x in the isoscleles triangle sqrt45 and altitude 3​
Alisiya [41]

Answer:

c.\hspace{3}x=12

Step-by-step explanation:

Isosceles triangles are a type of triangles in which two of their sides have an identical length. It should be noted that the angles opposite the sides that are the same length are also the same. This means that these triangles not only have two equal sides, but also two equal angles.

You can solve this problem using different methods, I will use pythagorean theorem. First take a look at the picture I attached.  As you can see:

x=2a

And we can find a easily using pythagorean theorem:

(\sqrt{45} )^{2} =3^{2} +a^{2}

Solving for a:

a^{2} =(\sqrt{45} )^{2} -3^{2} \\\\a^{2} =45-9\\\\

a^{2} =36\\\\a=\sqrt{36} \\\\a=6

Therefore:

x=2a\\\\x=2(6)\\\\x=12
