If f(x) = 2x + 3 and g(x) = x2-7, find (f+g)(x)

1 answer:

3 0

<span>f(x) = 2x + 3
</span><span>g(x) = x²-7

</span>(f+g)(x) = f(x) + g(x) = 2x + 3 + x² - 7 = x² + 2x - 4

(f+g)(x) = x² + 2x - 4

Who can finish this for me

Paladinen [302]

Answer:

Step-by-step explanation:

$(5 - 5 {x}^{4} - {x}^{3} ) - (6 {x}^{3} - 4 {x}^{4} - 3)$

Remove unnecessary parentheses

$5 - 5 {x}^{4} - {x}^{3} - (6 {x}^{3} - 4 {x}^{4} - 3)$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression

$5 - 5 {x}^{4} - {x}^{3} - 6 {x}^{3} + 4 {x}^{4} + 3$

Collect like terms

$5 + 3 - 5 {x}^{4} + 4 {x}^{4} - {x}^{3} - 6 {x}^{3}$

$5 + 3 - {x}^{4} - 7 {x}^{3}$

Add the numbers

$8 - {x}^{4} - 7 {x}^{3}$

Use the commutative property to reorder the terms

$- {x}^{4} - 7 {x}^{3} + 8$

Hope this helps...

Best regards!!
