Identify the features of the graph
1 answer:
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The graph represent a vertical parabola open up
The vertex is the minimum value of the parabola
The vertex is the point (3,-4)
The x-intercepts are the points (1,0) and (5,0)
The x-intercepts are the values of x when the value of y is equal to zero
The y-intercept is the point (0,5)
The y-intercept is the value of y when the value of x is equal to zero
The domain is the interval -----> (-∞,∞) All real numbers
The range is the interval -----> [-4, ∞) All real numbers greater than or equal to -4

An irrational number is a number that can't be written as a simple fraction while a rational number is a number that can be written as the ratio of two integers, that is, as a simple fraction. So in this case we have the number 2 which is ration, and we can multiply it by an irrational number such that the product is an irrational number. So any irrational number will meet our requirement because the product of any rational number and an irrational number will lead to an irrational number. For instance:
