Answer:
144
Step-by-step explanation:
" Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x).1. = [3x + 2] + [4 – 5x] = 3x + 2 + 4 – 5x. = 3x – 5x + 2 + 4. = –2x + 6. (f – g)(x) 2. = f (x) – g(x)= [3x + 2] – [4 – 5x] = 3x + 2 – 4 + 5x. = 3x + 5x + 2 – 4. = 8x– 2. 3. ...= (3x + 2)(4 – 5x) = 12x + 8 – 15x2 – 10x. = –15x2 + 2x + 8. " - Google
Answer:
12x
Step-by-step explanation:
It has no exponent so it is not a polynomial
We simply replace a with -9
k(-9) = 4 * -9 - 4
k(-9) = -40

Answer:
37
Step-by-step explanation:
f(x)=2x²−x+9
f(4)= 2(4)²-4+9
= 32-4+9
= 37
