(5, 3) is the solution to this ordered pair
That's 2³ = 8 that gives the number of subsets
Answer:
Choice A
Step-by-step explanation:
You take the x value and plug it into the formula to see if the answer lines up with the table
Answer:
Step-by-step explanation:
n = 3
3(n + 2) = 3(3+2) = 3*5 = 15
Answer:
f(x) = 2x² - 8x - 10.
This is a parabola open upward (since a>0) with an axis of symmetry = -b/2a:
a) axis of symmetry: x = -(-8)/(2*2) = 8/4 = 2. Then x = 2, which is the x component of the vertex
b) for x = 2, f(x) = f(2) = - 18 (component of y of the vertex)
c) VERTEX(2, - 18)
d) DISCRIMINENT: b² - 4.a.c = 64 - 4*2*(-10) = 144
Hope this helps! :)
