Answer:

[tex]\boxed{f[ g(3) ] = 673}[/tex]

Step-by-step explanation:

[tex]f(x) = 4x^2 - 3 \\ g(x) = 5x - 2[/tex]

[tex]f(g(3))[/tex]

[tex]f(5(3)-2)[/tex]

[tex]f(15-2)[/tex]

[tex]f(13)[/tex]

[tex]f(13)=4(13)^2 -3[/tex]

[tex]f(13)=4(169) -3[/tex]

[tex]f(13)=676-3[/tex]

[tex]f(13)=673[/tex]

Answer:

f[g(3)] = 673
