Answer:
f(7) - f(-7)
= (4 - 7^2) - ((-7)^3 - 2*(-7))
= -45 - (-329)
= 284
Here is the answer to the equation. The photo below is the work shown.
x^2-3x-18
First we need to find where the 2 graphs intercept.
x^2 + 3 = - (x^2 - 4x + 4) + 7
x^2 + 3 = -x^2 + 4x + 3
2x^2 - 4x = 0
2x(x - 2)
x = 0 , 2. are x coordinates of the 2 intercepts.
False... a ratio equivalent to 2:5 is 4:10
2/5 × 2/2 = 4/10
The answer I believe is the third choice.
3, -2, -7, -12
These all fit into f(n)-5=f(n+1)
