Y = 2x − 1

poizon [28]

Part A
y = 2x -1
the slope is 2/1 means it will be up 2 right 1 or down 2 left 1 the slope is positive
the y-int is -1

y = 4x -5
the slope is 4/1 means it will be up 4 right 1 or down 4 left 1 the slope is positive
the y-int is -5

part B
the solution to this is (2,3)

Plot the zeros of the function and select the correct end behavior of function's graph.

dem82 [27]

Answer:
As x approaches negative infinity, f (x) approached negative infinity

Explanation:
The graph of the given function is shown in the attached image.

Let's check the options given:
Option 1:
As x approaches positive infinity, f(x) approaches negative infinity.
This option is incorrect as we can note that as the value of x increases approaching positive infinity, the value of f (x) also increases approaching positive infinity

Option 2:
As x approaches negative infinity. f(x) approaches negative infinity.
This option is correct as we can note that as the value of x decreases approaching negative infinity, the value of f (x) also decreases approaching negative infinity

Option 3:
As x approaches negative infinity, f(x) approaches positive infinity.
This option is incorrect as we can note that as the value of x decreases approaching negative infinity, the value of f (x) also decreases approaching negative infinity

Option 4:
As x approaches positive infinity, f(x) remains constant.
This option is incorrect as we can note that as the value of x increases approaching positive infinity, the value of f (x) also increases approaching positive infinity

Hope this helps :)

A cube has a surface area of 96 square centimeters. How long is each face of the cube?

netineya [11]

Answer:

I believe the answer would be 4

Step-by-step explanation:

I'm going to use (a) to represent the side length in my explanation. side length is equivalent to the square root of the surface area over 6. The 6 is coming from there being 6 faces on a cube. So to solve this equation, you would first write it out. a=96/6. Next you would divide 96/6, giving you 16. and then lastly, you would find the square root of 16, which is 4. giving you a final answer of 4.

Hope this helps, and you understand it more!
