Answer 1

hey there, person with the same name as me lol. the answer is c. -2

Explanation:

in the question they showed that f(x) = 2x - 10

when they ask for the value of any number like f(4)

just replace the variable with this number

for this it will be

2x - 10 = 2 * 4 - 10

which is 8-10

which is equal to -2

you're welcome....

Answer 2

The answer is -2 or C

Explanation:

Just input 4 into the equation as x. f(4)=2(4)-10. This gets you 8-10 which is -2. Hope this helps!
