Answer 1

Answer:

If f(-3)

then

fx =2x-5

f(-3)=2(-3)-5

f(-3)=-6-5

f(-3)=-11

Answer 2

SOLUTION

GIVEN

$\sf \: f(x) = 2x - 5$

EVALUATION

Here the given function is

$\sf \: f(x) = 2x - 5$

Putting x = - 3 we get

$\sf f( - 3) = 2 \times ( - 3) - 5$

$\sf \implies \: f( - 3) = - 6 - 5$

$\sf \implies \: f( - 3) = - 11$

FINAL ANSWER

$\sf \: f( - 3) = - 11$
