Answer:
f(x)−g(x)=−6x^4+x^3+9x−9
Step-by-step explanation:
To find f(x) - g(x), subtract the expressions by distributing a negative into g(x) and combine like terms. Recall, like terms are terms which have the same base and exponent.
f(x) - g(x) = x^3 + 4x - 7 -(6x^4 - 5x + 2)
f(x) - g(x) = x^3 + 4x - 7 -6x^4 + 5x - 2
f(x) - g(x) = -6x^4 + x^3 + 9x - 9
