Which graph represents a function? A coordinate plane shows 4 points with the following coordinates: (negative 3, 3), (negative
Jet001 [13]

The ordered pair that represents a function is:

⇒ (-3, 3), (-2, -2), (1, 1), (2, -2)

<u>What are Coordinates?</u>

A pair of numbers that describe the exact position of a point on a cartesian plane by using horizontal and vertical lines are called the coordinates.

The given points are;

(-3, 3), (-3, -3), (-1, 1), (1, 4)

(-3, 3), (-2, -2), (1, 1), (2, -2)

(-3, 3), (-3, -3), (1, -4), (1, 1)

(-4, 4), (-4, 1), (-2, 1), (2, 1)

Now, For an ordered pair to be a function, either of the following must be true:

Each x-value has exactly one corresponding y-value.

More than one x-values have the same corresponding y-values.

And, If any of the following conditions is true, then the ordered pair is not a function,

One x-value has multiple corresponding y-values.

More than one x-values have multiple corresponding y-values.

From the given options, only ordered pair  (-3, 3), (-2, -2), (1, 1), (2, -2) satisfies the condition to be a function.

Because none of its x-values have multiple corresponding y-values.

And, Other ordered pairs are either one-to-many or many-to-many.

So, The ordered pair that represents a function is:

⇒  (-3, 3), (-2, -2), (1, 1), (2, -2)

A school uses the function p(t)=t2−20t+175 to model the profit (in dollars) expected in a weekend when the tickets are sold at a
Arte-miy333 [17]

Answer:

(a)\ t^2 - 20t  + 75= 0

(b) t = 5; t -=15

Step-by-step explanation:

Given

p(t) = t^2 - 20t  + 175

Solving (a): Equation when profit = 100.

This implies that:

p(t) =100

So, we have:

100 = t^2 - 20t  + 175

Rewrite as:

t^2 - 20t  + 175 - 100 = 0

t^2 - 20t  + 75= 0

Solving (b): Calculate t, in (a)

In a, we have:

t^2 - 20t  + 75= 0

Expand

t^2 - 15t -5t  + 75= 0

Factorize

t(t - 15) -5(t  - 15)= 0

Factor out t - 15

(t - 5)(t  - 15)= 0

Split

t - 5 = 0; t - 15 =0

Solve

t = 5; t -=15

<em>The prices are $5 and $15, respectively</em>
