Answer:
Step-by-step explanation:
f(x) = (x + 3)(x - 2) has two zeros: One stems from (x + 3) = 0 and is (-3, 0); the other stems from (x - 2) = 0 and is (2, 0).
The axis of symmetry is a vertical line located halfway between -3 and 2:
x = -1/2.
The graph opens up because the given (x + 3)(x - 2) has a positive leading coefficient (+1).
With this information we can eliminate the last two possible answers. Note that the x-intercepts of the first graph are -3 and 2, Thus, the first graph is the correct one.
Shaded=big rectangle-white rectangle
area recangle=base times height=(x+10) times (2x+5)=2x²+25x+50
area white=(x+1) times (x+1)=x²+2x+1
big-white=(2x²+25x+50)-(x²+2x+1)=
2x²+25x+50-x²-2x-1=
x²+23x+49
de area is x²+23x+49
