Let f(x) = 2x^2 + x - 3 and g(x) = x+ 2. Find (f • g) (x)

Step-by-step explanation:

f(x) = 2x² + x - 3

g(x) = x + 2

To find (f • g) (x) substitute g(x) into every x in f (x)

That's

(f • g) (x) = 2(x + 2)² + x + 2 - 3

Expand and simplify

(f • g) (x) = 2( x² + 4x + 4) + x - 1

= 2x² + 8x + 8 + x - 1

Group like terms

= 2x² + 8x + x + 8 - 1

We have the final answer as

Hope this helps you

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

i cant answer this, theres no table. sorry man
