Question

I need help 9th grade math

Answer 1

• (f-g)(x)
• f(x)-g(x)

Put values

• 2x+3-(3x+2)
• 2x+3-3x-2
• -x+1

Answer 2

-x + 1

Explanation:

f(x) = 2x + 3

g(x) = 3x + 2

we want to find (f-g)(x)

(f-g)(x) is the same as saying f(x) - g(x)

f(x) - g(x) = (2x + 3) - (3x + 2)

==> remove parenthesis and apply negative sign

f(x) - g(x) = 2x + 3 - 3x - 2

==> combine like terms

f(x) - g(x) = -x + 1
