Answer:
I think the answer is 2n-5
(-3n + 2)+(5n - 7)
-3n+5n=2n
2+(-7)=-5
I have attached an image explaining how to solve this problem.
(“m” means slope)
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.
F^1(-2) = 2(-2) = -4
f(-4) = 1/2 * -4 = -2
f(f^-1(x)) = x so answer is -2
