The answer is A. This can be seen in the table where y can be both 4 and 3 for when x = 3. In a function, an output can have more than one input, but an input can have have only one output.

Answer: A function is so F(X) = Y where for every X exist only one Y, in this case you can see that F(3) = 4 and F(3) = 3, so the independent variable x = 3, has two solutions y.

So the solution is A, because a function cannot have two different y values for one x value.

Answer:

x = 0, mult: 3
x = -4, mult: 2
x = -5, mult: 2

Step-by-step explanation:

When a polynomial is shown in factored form, its zeros are the values of x that make the factors zero.

The factor x is zero when x=0.

The factor (x+4) is zero when x=-4.

The factor (x+5) is zero when x=-5.

The multiplicity of a zero is the number of times a given factor is a factor of the polynomial. It is the exponent of the factor.

x = 0 has multiplicity 3.

x = -4 has multiplicity 2.

x = -5 has multiplicity 2.

A cable 20 feet long connects the top of a flagpole to a point on the ground that is 16 feet from the base of the pole. How tall

timurjin [86]

Think of it like a triangle.

The flagpole is vertical and is at 90° to the ground. This makes a right-angle to the ground, which is flat.

Since we have two sides of the triangle already, and they are in a ratio of ?? : 16 : 20 = ?? : 4 : 5, that means that because the triangle is a right-angled triangle, the third and last side must be 3 to complete the ratio! (This is called 'Pythagoras')

Since the other sides were divided by 4 to get the simple ratio, we must multiply 3 to get the actual ratio! 3 × 4 = 12 ft tall flagpole.
