Question

Dada a função f:R-R definida por f(x) = x elevado a 2 -5x+6, determine:
f(0)
f(2)
f(3)
f(4)

Answer 1

f(0) = 0^2 - 5.(0)+6= 6

f(2)=2^2-5.(2)+6  =  4-10+6   =0

f(3)=3^2-5.(3)+6= 9-15+6 =0

f(4)=4^2-5.(4)+6=  16-20+6 =2

Answer 2

Boa tarde!!
f(x) = x²-5x+6

f(0) = 0²-5.0+6
0-0+6
6

f(2) = 2²-5.2+6
4-10+6
-6+6
0

f(3) = 3²-5.3+6
9-15+6
-6+6
0

f(4) = 4²-5.4+6
16-20+6
-4+6
