what key features can be identified from graphs of polynomials with higher degrees and explain how the key features can be used
Natali [406]
Polynomials are algebraic expressions that contain more than two terms. AN example would be: f(x) = x^3 + x^2 + x +1. This equation contains three terms, with the 3rd degree as its highest term. It also means that the graph passed three x-intercepts. This depends in the highest degree. So, the first thing you do is plot the intercepts because for sure, the graph will pass there.

This question can be solved by applying the properties of similar triangles

the triangle with sides 5x and 20 is similar to the triangle with sides 45 and 35

The similarity property used here is called AAA ie angle angle angle property as all the three angles of the 2 triangles are equal.

therefore we can say

5x/45=20/36

x=5 units

Hope this helps

Given that f(x)= 9x^2-180, find x
hoa [83]
9x^{2}  - 180 = 0

9x^{2}  = 180

Divide both sides by 9

 x^{2} = 20

Square root both sides, and you get

x =  \sqrt{20} --\ \textgreater \  simplified: 2 \sqrt{5}
