All of them involve y intercepts
f(x) means y
g(x) means y
y intercept is where the graph crosses the y axis or when x=0 so set x=0
f(x)
x=0 when y=-7.5
y int=-7.5
g(x)
x=0
set x=0
y=3^0-7
y=1-7
y=-6
f(x) yint=-7.5
g(x) yint=-6
A. y int of f(x) is less than yint of g(x)
-7.5<-6
true
B. this is oposite of A so this is wrong
C. this says that g(x) has no yint, false
D. they yints are eqla
-7.5=-6
false
answer is A
Divide 4 by 12, which equals approximately 0.33333, then multiply that to 180, which gives us 60. So she sold 180 ears of corn for $60.
Probably y = 8x. 56 = 8(7), so that works. Without more data, I couldn't say if it could be something else, so that's what I go with.
