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
see the attached figure to better understand the problem
It’s Quadrant I. The Cosine and its reciprocal are positive in the first quadrant only.
