You can use the quadratic formula with it which will be easier
or simple factoring
it will be (5x-11)(7x+4)
Answer:
Step-by-step explanation:
4. f(x) = √(x + 4)
f(5) = √(5+4) = √(9) = 3
5. g(x) = x^12 - x^5
g(-1)= (-1)^12 - (-1)^5
1 - (-1) = 1 + 1 = 2
Yes...because every x value corresponds to exactly one y value
a function will not have any repeating x values...it can have repeating y values, just not the x ones. So if all the x values are different, then it is a function
