Cevap:

-1

Adım adım açıklama:

F (x) = 3cos2x-2sinx fonksiyonu verildiğinde, f (3π \ 2) bulacağız.

Vekil;

f (3π / 2) = 3kos2 (3π / 2) -2sin (3π / 2)

f (3π / 2) = 3cos3π - 2sin (3π / 2)

f (3π / 2) = 3 (-1) -2 (-1)

f (3π / 2) = -3 + 2

f (3π / 2) = -1

Dolayısıyla f (3π / 2) değeri -1'dir

If f(x)=4x2=1 and g(x)=x2-5, find (f-g)(x)<br>A:3x2+6<br>B:5x2-6<br>C:3x2-4<br>D:5x2-4

For this case we have the following functions:

$f (x) = 4x ^ 2 + 1\\g (x) = x ^ 2-5$

We must find $(f-g) (x):$

By definition of operations with functions we have:

$(f-g) (x) = f (x) -g (x)$

So:

$(f-g) (x) = f (x) -g (x) = 4x ^ 2 + 1- (x ^ 2-5) = 4x ^ 2 + 1-x ^ 2 + 5 = 3x ^ 2 + 6$

Answer:

Option A

$3x ^ 2 + 6$
