Question

Tolong yg no 3,5 sama 7 pake cara penyelesaiannya ya

Answer 1

3)
f(x)= x²
g(x) = 2x+1
h(x) = f(x) +g(x)
h(x) = x² + 2x + 1

h(x-1) = (x-1)² + 2(x-1) + 1
h(x-1) = x²-2x+1 + 2x -2 +1
h(x-1) = x² 

4) f(x) = sin 2x
g(x) = tan x
pada 0 < x < 1/2 π
.
h(x) = f(x) . g(x)
h(x) = sin 2x . tan x
h(x) = 2 sin x cos x  ( sin x / cos x)
h(x) = 2 sin² x

5. f(x)= ²log(x²+1)
g(x)= ²log(x²+2)
f(x) +g(x) = ²log(x²+1)(x²+2)
f(x)+g(x) = ²log(x⁴ + 3x² + 2)

6. f(x) = 2^(x+2)
g(x) = 8ˣ

h(x)= f(x)/g(x)
h(x) = (2². 2ˣ)/8ˣ
h(0)= (2².2⁰)/(2³ˣ)
h(x) =  2² 2⁻⁰. / 2⁰
h(x) = (4)(1)/(1)
h(X) = 4
