Answer:
Jamie, because 9 out of 10 is a 90 and 12 out of 15 is an 80
<span>
(-1 + -4x)(4 + -5x) = 0</span>
F(x) = 2x + 1 when x <= -5
Now -10 is less than -5 so we plug x = -10 into 2x +1:-
f(-10) = 2(-10) + 1 = -19 answer
Now f(x) = x^2 when -5< x < 5
x =2 is within this range so f(2) = 2^2 = 4 answer
You can calculate the other 3 values by a similar method
