Answer 1

Ответ:

$a)y = 2x \\ y = (2x) \\ y = 2 \\ b)y = {x}^{3 } + 2 \\ y = ( {x}^{ 3} + 2) \\ y = 3 {x}^{2} + 0 \\ y = 3x {}^{2} \\ y(5) = 3 \times 5 {}^{2} = 75 \\ y(8) = 3 \times 8 {}^{2} = 192 \\ d)y = (x - 2) {}^{2} \\ y = ((x - 2) {}^{2} ) \\ y = g {}^{2} \times (x - 2) \\ y = 2g \times 1 \\ y = 2(x - 2) \times 1 \\ y = 2x - 4 \\ y(5) = 2 \times 5 - 4 = 6 \\ y(8) = 2 \times 8 - 4 = 12 \\ g)y = x {}^{4} + 5x \\ y = (x {}^{4} + 5x) \\ y = (x {}^{4} ) + (5x) \\ y = 4x {}^{3} + 5 \\ y(5) = 4 \times 5 {}^{3} + 5 = 505 \\ y(8) = 4 \times 8 {}^{3} + 5 = 2053$
