Question

What is (f-g)(x)? Please show work, thank you.

Answer 1

x⁴ - x³ + 2x - 6

Explanation:

Apparently i cannot write the equation needed so we will call it r(x) and the 2 given equations, a(x) and b(x) respectively

r(x) is the same as a(x) - b(x)

a(x) - b(x)

= x⁴ - 3x² + 5x - 7 -(x³ - 3x² + 3x -1)

= x⁴- x³ + (- 3x² + 3x²) + (5x - 3x) + (- 7 + 1)

= x⁴ - x³ + 2x - 6
