Question

pffffff me ajudem agradeço

Answer 1

F[x] = 2x^2 + 5

F[5] = 2.5^2 + 5
f[5] = 2.25 + 5
f[5] = 50 + 5
f[5] = 55

F[-2] = 2.-2^2 +5
f[-2~= 2 . 4 +5
f[2] = 8 + 5
f[2] = 13

f[0] = 2.0^2 + 5
f[0] = 0 + 5
f[0] = 5

b]

f[0.3] = 2.0,3 ^2 +5
f [0,3] = 2. 0,09 + 5
f [0,3] = 0,18 + 5
f [0,3 ] = 5,18
