What relations does not represent an function?

a) {(3, 0), (0, 3)}

b) {(6, -2), (5, -2)}

c) {(3, 4), (3, 5)}

d) {(5, 5), (-5, -5)}

e) {(1, -2), (-2, 1)}

C) {(3, 4), (3, 5)}

Step-by-step explanation:

We know that,

'Function is a relation in which every element of the domain is mapped to a unique element in the co-domain'.

So, we get that,

In the ordered pair (x,y), the if 'x' is mapped to two values say y and z, then for the relation to be a function, y  must be equal to z.

So, according to the options, we see that,

In option C i.e. the relation {(3,4), (3.5)}, we have that, 3 does not have unique image i.e. it is mapped to 4 and 5 both.

Thus, this relation does not satisfy the definition of a function.

So, option C will not represent a function.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
