Alguien que me ayude a resolver estas graficas de las funciones polinomiales::
porfiss aunque no sean todas pero seria de mucha ayuda::
1.-f(x)=x33+x2-4x-4
2.-f(x)=x3+x2-22x-40
3.-f(x)=x3+x2-21x-45
4.-f(x)=x4-4x3-26x2+60x+225
5.-f(x)=2x3+5x2-11x-14
6.-f(x)=3x3+5x2-12x-20
7.-f(x)=x3+7x2+8x-16
8.-f(x)=x3-x2-14x+24
9.-f(x)=-x4+2x3+35x2-36x-180
10.-f(x)=-x4-cx3+6x2+28x+24

What two consecutive odd integers have a sum of -28

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.

1. the manager of collins import autos believes the number of cars sold in a day (q) depends on two factors: (1) the number of hours the dealership is open (h) and (2) the number of salespersons working that day (s). after collecting data for two months (53 days), the manager estimates the following log-linear model: q 4 equation 1 a. explain, how to transform the log-linear model into linear form that can be estimated using multiple regression analysis. the computer output for the multiple regression analysis is shown below: q4 table b. how do you interpret coefficients b and c? if the dealership increases the number of salespersons by 20%, what will be the percentage increase in daily sales? c. test the overall model for statistical significance at the 5% significance level. d. what percent of the total variation in daily auto sales is explained by this equation? what could you suggest to increase this percentage? e. test the intercept for statistical significance at the 5% level of significance. if h and s both equal 0, are sales expected to be 0? explain why or why not? f. test the estimated coefficient b for statistical significance. if the dealership decreases its hours of operation by 10%, what is the expected impact on daily sales?
