Answer:
f(x) = -7x² - x + 2
Step-by-step explanation:
Quadratic functions are set up in the form ax² + bx + c. f(x) = 0x² + 3x -3 is also set up in this format but 0x² would simplify to 0 which means the equation is actually f(x) = 3x-3 and does not fit in the quadratic function format. The other equations are also not set up in ax² + bx + c.
Answer:
15
Step-by-step explanation:
y = 5 l -1 + 4 l
-1 + 4 = 3
3 would not become -3 because positives stay a positive in the inverse operation thing.
5 times 3 is 15
So y is 15
