If f(x) = 2x2 - 2x + 7 and g(x) = x2 + 9x -6, what is f(x) - g(x)?
Solution:
Given the functions f(x) and g(x)
f(x) = 2x2 - 2x + 7
g(x) = x2 + 9x -6
We know that
f(x) - g(x) = (2x2 - 2x + 7) - (x2 + 9x -6)
On further calculation
= 2x2 - 2x + 7 - x2 - 9x + 6
So we get
= 2x2 - x2 - 2x - 9x + 7 + 6
= x2 - 11x + 13
Therefore, f(x) - g(x) is (x2 - 11x + 13).
If f(x) = 2x2 - 2x + 7 and g(x) = x2+ 9x -6, what is f(x) - g(x)?
Summary:
If f(x) = 2x2 - 2x + 7 and g(x) = x2 + 9x -6, f(x) - g(x) is (x2 - 11x + 13).
