Question

dada a função f(×) -3×+2 calcule f(2) +f(-3)

Answer 1

Boa tarde

f(x) = -3x + 2

f(2) = -3*2 + 2 = -6 + 2 = -4 
f(-3) = -3*(-3) + 2 = 9 + 2 = 11

f(2) + f(-3) = -4 + 11 = 7 

Answer 2

dada a função f(×) -3×+2 calcule f(2) +f(-3)

F(2)

F(X) = -3X + 2
Y = -3*2 + 2
Y = -6 + 2
Y = -4

F(-3)

F(X) = -3X + 2
Y = -3 (-3) + 2
Y = 9 + 2
Y = 11

F(2) + F(-3) = -4 + 11 = 7
