Answer 1

f(-2)=3(-2) +4

f(-2)=-6+4

f(-2)=-2

Answer 2

For this case we have a function of the form:

$y = f (x)$

Where $f (x) = 3x + 4$

If we have the value of$x = -2$, substituting we have:

$f (-2) = 3 (-2) +4$

We solve the multiplication taking into account that + * - = - and $3 * 2 = 6$

$f (-2) = - 6 + 4$

It is known that different signs are subtracted and the sign of the major is placed.

$f (-2) = - 2$

Thus,$f (x) = 3x + 4$ evaluated at $x = -2$is:$f (-2) = - 2$

Answer:

$f (-2) = - 2$
