Answer:
A, D, F
Step-by-step explanation:
A. True, because represents quadratic function (the greatest power of x is 2)
B. False, because this function is quadratic, so cannot be linear
C. False. The vertex of the parabola is at point (-7,4) (see diagram)
D. True. The axes of symmetry is the line x=-7 that passes through the vertex.
E. False. The y-intercept is at point x=0 and
F. True. The graph has the maximum at vertex, where
G. False. The graph of the parabola intersects the x-axis at two points (-9,0) and (-5,0), so x=-9 and x=-5 are two real solutions of the equation f(x)=0.
Answer:
Option (2)
Step-by-step explanation:
If two chords intersect inside the circle, measure of angle between them is half of the sum of intercepted arcs.
From the picture attached,
m∠MPN =
=
= 75°
Therefore, Option (2) will be the answer.
