Not a function. See below the explanation.

Step-by-step explanation:

Function is a set of relation with different domains. That means we cannot have same or repetitive domain in one set.

Domain is the set of all x-values. So we only focus on x-term. From the table, we notice that there are two same domains which are - 7. Function cannot have the same or repetitive domain.

Therefore, not a function.

no.

I'll explain to u in easy way❤️

any x has to have exactly one function f(x)

we can see that same x value (-7) has two different y values

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
