diketahui f(x)=2-x , g(x)=x²+1 , dan h(x)=2x . maka jika [ho(gof)](5) adalah

di cari gof nya dulu
gof= g(f(x)
[tex]gof = {(2 - x)}^{2} + 1[/tex]
gof = (2-x)(2-x)+1
gof = 4-2x-2x+x^2 +1
gof = 5-4x+x^2

ho(gof) = h (gof(x)
= 2(5-4x+x^2)
= 10-8x+2x^2

ho(gof) (5) = 10-8(5)+2(5)^2
= 10-40+50
= 60-40
= 20
di like ya semoga membantu
