Answer:
52 in^2
Step-by-step explanation:
The answer is A=1 b=40 c=24
Since it's not a domain restricted function anywhere, the domain of this function is (-∞, ∞). Because the x is squared, you will <em>never </em>get a negative answer, and therefore, the range is either (0, ∞) or {x: x > 0}. Hope this helps you out!
Start by seeing where the lines go. They cross (intersect) at (1, -1). We can use this to check later.
Now for slope: green is -4/2 = -2
pink is 4/2 = 2
Now we can create the equations
Let's make green = g(x) and pink = p(x)
if we use y = mx + b, then the green has a y-intercept (b) of +1
So g(x) = -2x + 1
pink has a y-intercept of -3, so p(x) = 2x - 3
Now let's plug n play: put our solutions x into each equation and confirm that it makes the y = -1
g(x) = -2x + 1 = -2(1) + 1 = -2+1 = -1
p(x) = 2x - 3 = 2(1) - 3 = 2-3 = -1
✔ YES THEY ARE CONFIRMED
