Given:

4 relations in the options.

To find:

The relation which represents a function.

Solution:

We know that, a relation is a function if there exist a unique output value for each input value.

In option A, we have two output values y=-5 and y=1 for single input value x=-1. So, it is not a function.

In option B, we have two output values y=2 and y=4 for single input value x=3. So, it is not a function.

In option C, we have two output values y=1 and y=7 for single input value x=-1. So, it is not a function.

In option D, we have unique output value for each input value. So, it is a function.

Therefore, the correct option is D.

Answer:

The slopes of line segments AC and AD are same or constant i.e \frac{1}{3}

Step-by-step explanation:

We need to find slopes of AC and AD and tell if they are same or not.

The formula used to calculate slope is: Slope=\frac{y_2-y_1}{x_2-x_1}

Finding slope of AC

We have A=(3,2) and C=(0,1)

Finding slope using formula:

We have x_1=3, y_1=2, x_2=0,y_2=1

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{1-2}{0-3}\\Slope=\frac{-1}{-3}\\Slope=\frac{1}{3}

So, Slope of AC is \frac{1}{3}

Finding slope of AD

We have A=(3,2) and C=(9,4)

Finding slope using formula:

We have x_1=3, y_1=2, x_2=9,y_2=4

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{4-2}{9-3}\\Slope=\frac{2}{6}\\Slope=\frac{1}{3}

So, Slope of AD is \frac{1}{3}

So, the slopes of line segments AC and AD are same or constant i.e \frac{1}{3}

Which of the following is the graph of f(x) = x2 + 3x − 4?
xenn [34]

Answer:

2nd graph

Step-by-step explanation:

Given

f(x) = x² + 3x - 4

To find the zeros let f(x) = 0 , that is

x² + 3x - 4 = 0 ← in standard form

(x + 4)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 1 = 0 ⇒ x = 1

The only graph with zeros at x = - 4 and x = 1 is the 2nd graph
