f dan g fungsi fungsi dalam R,f(x)=4x2-10 dan g(x)=8x+1. nilai (f o g)(x) adalah

langsung aja y

(fog)(x) = f{g(x)}

= 4g(x)² - 10
= 4(8x+1)² - 10
= 4(64x² + 16x + 1) - 10
= 256x² + 64x + 4 - 10
= 256x² + 64x - 6

semoga berguna +_+

fog(x)=f(g(x)
=f(8x+1)
=4x²-10
=4((8x+1)(8x+1))-10
=4(64x²+8x+8x+1)-10
=4(64x²+16x+1)-10
=256x²+64x+4-10
=256x²+64x-6
