1,110,000.
You look at the ten thousands value and look at the number after it. If it is less than 5 then it is that number, just add zeros to the rest of the values after it.
B should be the answer Hope this helps.
7) Vertex = V(2,3)
9) Vertex = V(2,1)
17) The smaller the absolute value of the coefficient of x², the larger is the opening of the parabola. (to compare, just take the absolute value of a)
Coefficients are (5), (-3) and (1):
Widest: f(x) =x², followed by f(x) = -3x² and the narrowest is f(x) =5x².
