Question

Dada a função f(x) =2x+1
Calcule
A. F(0)
B. f(7)
C. f(-2)
D. F(-5)
E. F(3)
F. F(-1)

Alguem me ajuda!!

Answer 1

f(x) = 2x + 1
a) 
f(0) = 2.0 + 1    f(0) = 1
b)
f(7) = 2.7 + 1    f(7) = 14 + 1    f(7) = 15
c)
f(-2) = 2.(-2) + 1   f(-2) = - 4 + 1   f(-2) = - 3
d)
f(-5) = 2.(-5) + 1   f(-5) = - 10 + 1   f(-5) = - 9
e)
f(3) = 2.3 + 1   f(3) = 6 + 1   f(3) = 7
f)
f(-1) = 2.(-1) + 1   f(-1) = - 2 + 1   f(-1) = - 1
