Use the domain and range of each of the following relations to determine which is a function.

and if you could also answer the question below it would

b. is the only set of points that is a function.

Step-by-step explanation:

A relation is a function is there is not more than one y assigned to a x.

A relation relates a variable to another variable. Option a does not not this.

A set of points is a relation. A trick to figuring out if is a function is to see if all x's are different.

Let's look at b. All the x's are different there so it is a function.

Now c, we see that there are two different points with the same x so this is not a function.

Now d, we see that there are two different points with the same x so this is not a function.

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
