Pls help me. I have to state whether each graph is a function?.

Step-by-step explanation:

1 no.. not continuous

2no.. not continuous

3 yes , over a certain range it is

4no b/c it fails the vertical line test.. there is more than one point on the x axis

5no  multiple point on the x axis and not continuous

6 yes, over a certain range

i am sure it will be 90 degrees.

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
