How many x intercepts appear on the graph of this polynomial function?
f(x) = x^4 - 5x^2
a) 1 x intercept
b) 2 x intercepts
c) 3 x intercepts
d) 4 x intercepts

Option C -3 x-intercept

Step-by-step explanation:

Given : Polynomial function

To find : How many x intercepts appear on the graph of this polynomial function?

Solution :

To find the x-intercept we put y equals to zero.

Let

Now, Substitute y=0

We solve for x,

So,

Which means there are three x-intercept.

Therefore, Option C is correct.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
