1st month +450
-60 x 4 months = -240
6th month + 125
Total: 450 - 240 + 125 = $335 profit
A
this is because it is not infinite since there are not arrows and domain is all the possible c values while range is all the possible y values. Therefore when analyzing the graph we can see it starts at x=2 and ends at x=10 which is the domain. we can also see the lowest y value is 1 while the highest is 3 which is the range :)
Step-by-step explanation:
Part A:
4x² - 7x - 15
a, b, c = 4, -7, -15
ac = -60
factors that add up to -7 and multiply to -60 are (-12, 5)
rewrite equation
(4x² - 12x) + (5x - 15)
factor out GCF from both groups
4x(x - 3) + 5(x - 3)
(4x+5)(x-3)
Part B:
Using the factored form from the previous part we can set both factors equal to 0 to solve for x.
4x+5 = 0
4x = -5
x = -5/4
x-3 = 0
x = 3
the two x-intercepts are -5/4 and 3
Part C:
Since the leading coefficient is positive, the right side of the function will be going up or to positive infinity as x goes towards positive infinity. Since the degree is even both sides go in the same direction so on the left side it also goes towards positive infinity as x goes towards negative infinity.
I don't see a table lol, link it and I'll solve it
