Hitunglah nilai semua fungsi dengan menggunakan skema. 1. P(-3) jika p(x)=x^3-8x+3 2. F(-2) jika f(x)=7x^4-20x^2+15x+2 3.G(-1) jika g(x)=5x^4+7x^2+3x+1 4.H(5) j

1.
[tex]p( - 3) = { - 3}^{3} - 8( - 3) + 3 \\ p( - 3) = - 27 + 24 + 3 \\ p( - 3) = 0[/tex]
2.
[tex]f( - 2) = 7( { - 2}^{4} ) - 20( { - 2}^{2} ) + 15( - 2) + 2 \\ f( - 2) = 7(16) - 20(4) - 30 + 2 \\ f( - 2) = 4[/tex]
3.
[tex]g( - 1) = 5( { - 1}^{4} ) + 7( { - 1}^{2} ) + 3( - 1) + 1 \\ g( - 1) = 5 + 7 - 3 + 1 \\ g( - 1) = 10[/tex]
4.
[tex]h(5) = {5}^{3} + 7( {5}^{2} ) - 4(5) + 3 \\ h(5) = 125 + 175 - 20 + 3 \\ h(5) = 283[/tex]
