The x value of the vertex in
ax^2+bx+c is -b/2a
y value is just sub for x
3x^2-6x+5
x value of vertex is -(-6)/(2*3)=6/6=1
sub back
y=3(1)^2-6(1)+5
y=3(1)-6+5
y=3-1
y=2
vertex is (1,2)
The first one, 4x is the slope and the +3 is the y-intercept
I cant help with too much because im 14 and in the 8 th grade but for part c the answer is 200 dollars. If you have 100 bracelets and your selling them for 2 dollars a bracelet the answer will be 200 hundred dollar profit.
