Answer:
Second graph only.
Step-by-step explanation:
The standard equation of a parabola is ax^2+bx+c where a,b and c are coefficients.
If the coefficient of (a) is positive then the parabola is concave upwards (as in picture 1)
If the coefficient of (a) is negative then the parabola is concave downwards as in picture 2.
Its the second and third graphs only
y=-x+2
Y intercept = 2
Slope = -1/1 = 1
y=-1x+2
Simplified
c
470,925.8 in expanded form is ...
400,000 + 70,000 + 900 + 20 + 5 + 0.8
