Answer:
164m (to 3 s.f.)
Step-by-step explanation:
Please see the attached picture for the full solution.
I've searched online on what a graph look like in each given function and based on my online search, the given image of of the equation f(x) is a CUBIC FUNCTION.
A cubic function is like this: f(x) = ax³ + bx² + cx + d
The given graph can have this equation:
y = (x + 1) (x - 1) (x - 3)
-k-(-8k)
= -k + 8k (two negatives equal one positive)
= 8k-k (flip it around because of the commutative property)
=7k (basic subtraction)
I really hope that helped :)
