jika di ketahui f(x)²=x²+3x-2 a.f(2x+1)

Langsung aja y

f(x) = x² + 3x - 2

f(2x+1) = (2x+1)² + 3(2x+1) - 2
f(2x+1) = 4x² + 4x + 1 + 6x + 3 - 2
f(2x+1) = 4x² + 10x + 2

semoga berguna +_+

f(x)^2 = x^2+3x-2 (turunkan)
2f(x) = 2x +3
f(x) = (2x+3)/2
f(2x+1) = (2(2x+1)+3)/2
= (4x+2+3)/2
= (4x+5)/2
= 2x + 5/2
