Hello :
<span>f(x) = (-1)^x
if x=3
f(3) = (-1)^3 = -1</span>
Answer:
286
Step-by-step explanation:
Fiction = F
Nonfiction = N
N + F = 312
F = 11N
Substitute
N + 11N = 312
12N = 312
N = 26
F = 11N
F = 11* 26
F = 286
<u>Graph the parabola using the direction, vertex, focus, and axis of symmetry.</u>
Vertex:
(2,−2)
Focus:
(2,−74)
Axis of Symmetry:
x=2
