Question

1-Seja f(x)= 6x+ 5, determine : a)f(1) b)f(-1)

Answer 1

Explicação passo-a-passo:

a)

f(1) = 6.1 + 5

f(1) = 6 + 5

f(1) = 11

b)

f(-1) = 6.(-1) + 5

f(-1) = -6 + 5

f(-1) = -1

Answer 2

$\boxed{f(x) = 6x + 5}$

$a) \\ f(1) = 6 \: . \: 1 + 5 = 6 + 5 = \boxed{\boxed{\boxed{11}}}$

$b) \\ f( - 1) = 6 \: . \: ( - 1) + 5 = - 6 + 5 = \boxed{\boxed{\boxed{ - 1}}}$
