Find the difference quotient, f(x)=3x^2+8x+3x PLease show your work in your answer

1 answer:

8 0

If you mean (x^3-8x)-(3x-2) then:
1) leave the (x^3-8x) part alone and use the distributive property on the -(3x-2). 
2) your question now becomes x^3-8x-3x+2 
3) combine the like terms: x^3-11x+2

Over what interval will the immediate value theorem apply

koban [17]

Answer:

Any [a,b] that does NOT include the x-value 3 in it.

Either an [a,b] entirely to the left of 3, or

an [a,b] entirely to the right of 3

Step-by-step explanation:

The intermediate value theorem requires for the function for which the intermediate value is calculated, to be continuous in a closed interval [a,b]. Therefore, for the graph of the function shown in your problem, the intermediate value theorem will apply as long as the interval [a,b] does NOT contain "3", which is the x-value where the function shows a discontinuity.

Then any [a,b] entirely to the left of 3 (that is any [a,b] where b < 3; or on the other hand any [a,b] completely to the right of 3 (that is any [a,b} where a > 3, will be fine for the intermediate value theorem to apply.

The district manager of four different restaurants wanted to investigate whether the four restaurants differed with respect to c

Alex_Xolod [135]

Answer:

Hello your question is incomplete attached below is the complete question

answer : There is not convincing statistical evidence to suggest that the proportion of customers who order dessert at each restaurant is not the same based on family classification. ( E )

Step-by-step explanation:

To arrive at this conclusion we will determine the Null and alternate hypothesis

H0 : Number that orders dessert is same based on family classification given

Ha : Number that orders dessert is not the same based on family classification given

from the question the p-value of Chi-square test is 0.092 > 0.05 hence we will fail to reject the null hypothesis. therefore we can conclude that

There is not convincing statistical evidence to suggest that the proportion of customers who order dessert at each restaurant is not the same based on family classification
