If f(x)=x+3 and g(x)=2x^2 find (f+g)(x) and (f+g)(3)

1 answer:

8 0

Answer:

Given f (x) = 2x, g(x) = x + 4, and h(x) = 5 – x3, find (f + g)(2), (h – g)(2), (f × h)(2), and (h / g)(2). This exercise differs from the previous one in that I not only have to do the operations with the functions, but I also have to ...

Which of the following statements Is true concerning f(x)=x^2-2x-24?

Novosadov [1.4K]

Answer:

None of the given options is correct.

Step-by-step explanation:

Given:

$f(x)=x^2-2x-24$

To find:

the true statement

Solution:

$f(x)=x^2-2x-24$

Here,

$-2=-6+4$

$f(x)=x^2-6x+4x-24\\=x(x-6)+4(x-6)\\=(x+4)(x-6)$

To find the zeroes of $f(x)$ , put $f(x)=(x+4)(x-6)=0$

$(x+4)(x-6)=0\\x+4=0\,,\,x-6=0\\x=-4,6$

So, zeroes are $-4$ and $6$

None of the given options is correct.

andrey2020 [161]

Answer:

$3,10,29,66,127,218$

Step-by-step explanation:

$f(n) = n^3 +2\\\\f(1) = 1^3 +2 = 1+2=3\\\\f(2) =2^3 +2 = 8+2=10\\\\f(3)=3^3 +2 = 27+2 = 29\\\\f(4) = 4^3 +2 = 64 +2 = 66\\\\f(5) = 5^3 +2 = 125+2 = 127\\\\f(6) = 6^3 +2 = 216+2 = 218$
