Answer:
f(x) = -5x + 16
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
y + 5x = 16
Step 2: Put into slope-intercept form
- Subtract 5x on both sides; y = -5x + 16
Step 3: Rewrite in function notation
f(x) = -5x + 16
Your taking off $20 from the amount that you have to begin with
Answer:yea yea
Step-by-step explanation:
The x-intercept represents the points in which the quadratic function passes through the x-axis. The maximum value represents the ordered pair with the highest range(y-value).
Interval increasing: (Negative Infinity-10)
Interval Decreasing: (10-Negative Infinity)
Part B: 8/5
Note: I am assuming the scale factor of the graph is 2.
