diketahui g(x) = 2x - 3 dan (gof)(x) = 4x^2-4x+5. nilai dari f(2) adalah

(gof)(x) = 4x² - 4x + 5
g(f(x) = 4x² - 4x + 5
2(f(x) - 3 = 4x² - 4x + 5
2(f(x) = 4x² - 4x + 5 + 3
2(f(x) = 4x² - 4x + 8
f(x) = (4x² - 4x + 8)/2
f(x) = 2x² - 2x + 4

f(2) = 2(2)² - 2(2) + 4
f(2) = 2(4) - 4 + 4
f(2) = 8 - 4 + 4
f(2) = 8
