Answer:
See explanations below
Explanation:
Vertex of a graph is the lowest point on the curve. The vertex occurs at (1.75, -2.5)
The axis of symmetry is the point on the x axis of the line that cuts through the minimum point. The axis of symmetry occurs at x = 1.75
x intercept is the point where the curve cuts the x axis. The x intercept occurs at x = 0 and x = 2.5
To get the minimum, we will use the formula;
c - b^2/4a
The equation of the curve is expressed as;
(x-0)(x-2.5)
= x (x-2.5)
= x^2 - 2.5x
a = 1, b = -2.5, c = 0
minimum = 0 - (-2.5)^2/4(1)
minimum = -6.25/4
minimum = -1.5625
Minimum value occurs at the base of the parabola. The minimum value of the function is -2.5
y intercept is the point where the curve cuts the y axis. The y-intercept occurs at y = 0.
Answer:
see below
Step-by-step explanation:
The points (–2, 3) and (–2, –3) are reflected across the x axis because the y value is the opposite
The points (–3, 5) and (3, 5) are reflected across the y axis because the x value is the opposite
The points (4, –2) and (2, 2) are reflected across y =x-3. We find this by drawing a line equidistant between the points and calculating the slope and the y intercept of the line.The slope is 1 and the y intercept is -3
The cost for 6 tickets is 40*6/5=48.
