Respuesta :
f(-2) = -7
f(7) = 11
f(-4) = -11
Given function,
f(x) = 2x - 3
We need to find f(x) at x = -2. 7 and -4.
We have,
f(x) = 2x - 3
Putting x = -2
We get,
f(-2) = 2 x (-2) - 3
= -4 - 3
= -7
Putting x = 7
we get,
f(7) = 2 x 7 - 3
= 14 - 3
= 11
Putting x = -4
We get,
f(-4) = 2 x (-4) - 3
= -8 - 3
= -11
Thus,
f(-2) = -7
f(7) = 11
f(-4) = -11
