Question

Evaluate the following function from this rule:
$f(x) = \left \{{2x + 10}$

$f(5)=\\f(-4)=$

If you need help ask me here :)!

Answer 1

Answer:

f(5) = 20

f(-4) = 2

Step-by-step explanation:

I assume the equation is f(x) = 2x + 10  (Not sure why the "{" is there.)

f(5) = 2*5+10

f(5) = 20

f(-4) = 2*(-4) + 10

f(-4) = 2
