Answer:
2x³-3x²+4
Step-by-step explanation:
F(x) = 2x-1
g(x)=x²-2
g.f(x) = (x²-2)(2x-1)
open the bracket
x²(2x-1)-2(x²-2)
2x³-x²-2x²+4
2x³-3x²+4
Answer:
Find the Least Common Denominator (LCD) of all the denominators in the complex fractions.
Multiply this LCD to the numerator and denominator of the complex fraction.
Simplify, if necessary.
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have the points (4, 1) and (2, 5). Substitute:
![m=\dfrac{5-1}{2-4}=\dfrac{4}{-2}=-2](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B5-1%7D%7B2-4%7D%3D%5Cdfrac%7B4%7D%7B-2%7D%3D-2)
<h3>Answer: The slope is -2.</h3>
Three fractions that are generated than 1/2 but less than one are 3/4, 4/5, 8/9
3.3333333333..... is the answer
