Question

ayudenme a resolver esto y también me lo explican porfaaaaa

Answer 1

1 ) f(x) = 4x - 7
f(0) = 4(0) - 7
f(0) = -7

f(2) = 4(2) - 7
f(2) = 8 - 7
f(2)= 1

2) f(-3)= -7(-3) + 8
f(-3) = 21 +8
f(-3) = 29

f(4) = -7(4) + 8
f(4) = -28 + 8
f(4) = -20

3) f (0) = (3(0) - 2)^3
f(0) = (0-2)^3
f(0) = (-2)^3
f(0) = -8

f(3) = (3(3) - 2)^3
f(3) = (9-2)^3
f(3) = (7) ^3
f(3) = -343

Es simple solo remplazar el valor de x
