1 pound = 16 oz
Her books weigh 9 pounds or (9)(16)= 144 oz
Math Textbook= 40 oz
Biology textbook= 3 pounds or (3)(16)= 48 oz

Total weight of books - math textbook - biology textbook = science textbook
144-40-48 = 56oz
science textbook = 56oz

F(x)=20-x^2+8x<br> what are the minimum and maximum points and the axis of symmetry?
-Dominant- [34]
Vertex aka max or min point is found by -b/2a in form
f(x)=ax^2+bx+c
f(x)=-1x^2+8x+20
vertex x value is -8/(2)(-1)=-8/-2=4
input back to find y value
f(4)=-(4^2)+8*4+20
f(4)=-16+32+20
f(4)=36
max (since the graph opens down) is (4,36)
axis of symmetry is the x coordinate


max is (4,36)
axis of symmetrry is x=4
