Answer:
As x approaches ∞, y approaches -∞
As x approaches -∞, y approaches ∞
Step-by-step explanation:
![f(x) = -x^5 + 9x^4 - 18x^3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-x%5E5%20%2B%209x%5E4%20-%2018x%5E3)
F(x) is a fifth degree (odd function ) with negative leading coefficient
If exponent is odd and leading coefficient is negative then end behavior is
As x approaches ∞, y approaches -∞
As you go on the right , f(x) goes down
As x approaches -∞, y approaches ∞
As you go on the left , f(x) goes up
This is an isosceles triangle. The angles at the base are congruent (they have the same measures).
Look at the picture.
We know: The sum of the measures of angles in a triangle is equal 180°.
Therefore we have the equation:
<em>combine like terms</em>
![(2x+2x+3x)+(-10-10+25)=180](https://tex.z-dn.net/?f=%282x%2B2x%2B3x%29%2B%28-10-10%2B25%29%3D180)
<em>subtract 5 from both sides</em>
<em>divide both sides by 7</em>
![x=25](https://tex.z-dn.net/?f=x%3D25)
![m\angle A=2x-10\to m\angle A=2(25)-10=50-10=40\\\\m\angle C=m\angle A=40\\\\m\angle B=3x+25\to m\angle B=3(25)+25=75+25=100^o](https://tex.z-dn.net/?f=m%5Cangle%20A%3D2x-10%5Cto%20m%5Cangle%20A%3D2%2825%29-10%3D50-10%3D40%5C%5C%5C%5Cm%5Cangle%20C%3Dm%5Cangle%20A%3D40%5C%5C%5C%5Cm%5Cangle%20B%3D3x%2B25%5Cto%20m%5Cangle%20B%3D3%2825%29%2B25%3D75%2B25%3D100%5Eo)
