Answer:
The correct answer is D. The reason is because you can name an angle by its middle letter or number if they intercept
Step-by-step explanation:
well, x-intercept means for a graphed funciton where the x-axis gets touched/intercepted, Check the picture below, when that occurs, y = 0, so if we want to know what "x" is at that point we can simply set y = 0 and solve for "x".
![-3x-5y=12\implies \stackrel{\textit{setting y = 0}}{-3x-5(0) =12}\implies -3x-0=12 \\\\\\ -3x=12\implies x=\cfrac{12}{-3}\implies x = -4 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{\textit{coordinates}}{(-4~~,~~0)}~\hfill](https://tex.z-dn.net/?f=-3x-5y%3D12%5Cimplies%20%5Cstackrel%7B%5Ctextit%7Bsetting%20y%20%3D%200%7D%7D%7B-3x-5%280%29%20%3D12%7D%5Cimplies%20-3x-0%3D12%20%5C%5C%5C%5C%5C%5C%20-3x%3D12%5Cimplies%20x%3D%5Ccfrac%7B12%7D%7B-3%7D%5Cimplies%20x%20%3D%20-4%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20~%5Chfill%20%5Cstackrel%7B%5Ctextit%7Bcoordinates%7D%7D%7B%28-4~~%2C~~0%29%7D~%5Chfill)
Answer:
1st option
Step-by-step explanation:
From the graph the zeros are x = - 3 and x = 1 , then the corresponding factors are
(x + 3) and (x - 1) , so
y = a(x + 3)(x - 1) ← a is a multiplier
To find a substitute a point on the graph into the equation
Using (0, - 1.5 ) , then
- 1.5 = a(3)(- 1) = - 3a ( divide both sides by - 3 )
0.5 = a
Then
f(x) = 0.5(x + 3)(x - 1)
2/4 = 0.5
3/4 = 0.75
7/8 = 0.875
3/8 = 0.375
I think the answer is unpaid balance
