Answer:
1/8
Step-by-step explanation:
F (5x^2 - 1) = 75x^4 - 35x^2 + 6
(2x-3)(x+5)
Use foil to simplify, First multiply together the first terms of the pairs, then the outer terms, the middle terms, and finally the last terms. Then combine like terms.
2x^2+10x-3x-15 equals 2x^2+7x-15
The answer is 150 over 100 hope this helps
Yes, a quadratic model does exist and its equation is f(x)=4x^2
