Alex

Answer:

Interval for the function has local minimum of 0 is [2,4].

Step-by-step explanation:

You need to find the local minimum of 0 in the given function's graph.

In mathematics, local minimum is a point on a graph whose value is less than all other points near it.

See that, graph value 0 is lie on the x = 3 and in interval x = 2 to x = 4

So, final answer is :

Interval for the function has local minimum of 0 is [2,4].That's the final answer.

Here are the first five terms of a sequence.
Snezhnost [94]

Step-by-step explanation:

3 to 8= 5

8 to 17= 9

17 to 30= 13

30 to 47= 17

47 to 68= 21

68 to 93= 25

93 to 122= 29

122 to 155= 33

155 to 192= 37

difference is 4

solve by

2 {n}^{2}  - n + 2 \\ 2 {(9)}^{2}  - 9 + 2 \\ 2(81) - 9 + 2 \\ 162 - 9 + 2 \\ 153 + 2 = 155

Order the polynomial -x 4 y 2 + 7x 3 y 3 - 3xy 5 + 2x 2 y 4 in descending powers of x.
bulgar [2K]

put all the combos together first like -3xy

then the x's like -x + 7x +2x=8x

then the y's

then the whole numbers

-3xy+8x (then the y's) then the whole numbers.

I am not sure how you are writing the numbers above like -x 4 is that -x to the 4th power?

x^4 then the x^3 and so forth then the y's then the whole numbers.

Always start adding the highest x power numbers first like x^4 + 2x^4=3x^4 then work your way down. Maybe rewrite the problem please.
