Which statements correctly describe the graph of the function f(x) = x3 – 2x2 - 19x + 20? Select three options. As the x-values increase, the y-values always increase.
As x approaches negative infinity, y approaches negative infinity.
O The domain of the function is all real numbers.
The range of the function is y > 20.
The graph has a positive y-intercept.

See below for answers and explanations (along with a graph for reference)

Step-by-step explanation:

A is true because the end behavior shows that as x gets larger, y also gets larger

B isn't true because that is an incorrect interpretation of the end behavior while the statement itself is true.

Any real value of x can be defined on the graph with an output, therefore C is also correct.

D is not true because that would contradict option C which we said was right since the domain and range are both all real numbers.

E is true because the y-intercept of the graph is (0,20) which is positive (marked in purple)

i dont know sorry

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
