Domain: {-1}
Range: {0, 4, 9, 15}
Function? No
Explanation:
The domain is the x value in the given points. The only x value is -1.
The range is the y value in the given points.
You can tell if this is a function if it has repeating x values or not. Since the x value of -1 repeats, it is not a function.

Answer:
if this is high school i cant do it
The constant should be added to form a perfect square trinomial will be 1/4. Then the correct option is D.
<h3>What is a quadratic equation?</h3>
It's a polynomial with a value of zero. There exist polynomials of variable power 2, 1, and 0 terms. A quadratic equation is an equation with one statement in which the degree of the parameter is a maximum of 2.
The expression is x² + x.
Then the constant should be added to form a perfect square trinomial.
Then the constant will be
The square of the half of the coefficient of the variable x is to be added to make a perfect square.
Then the constant will be 1/4.
Then the perfect square will be

Answer:
The actual tower would be 45 ft wide.
Step-by-step explanation:
In order to find the width, we need to determine the scale factor. We can do that by dividing the actual height by the model height.
60ft:24in = 15ft:6in = 2.5ft:1in
Now we use that scale factor to determine the width. Multiply the scale factor by the width of the model.
18 inches * 2.5ft/in = 45 feet
