Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20
88 pages = 352 minutes
1 page = 352/88 = 4 minutes
4 minutes = 240 seconds.
For Faye to read 1 page, it took her 240 seconds

Answer:
144
Step-by-step explanation:
Y=f(x) between x=a and x=b, integrate y=f(x) between the limits of a and b
