Question

If f(x)= 2x-5, then what is the value of f(2) + f(5)

Answer 1

Answer:  f(2) + f(5)  is 4.

Step-by-step explanation:

First input the values for x and solve for f(x) and then add their results.

f(2) = 2(2) -5

f(2) = 4 - 5

f(2) = -1

f(5) = 2(5) - 5

f(5) = 10 -5

f(5) = 5

Now add the results which is -1 and 5

-1 + 5 = 4

Answer 2

Answer:

4

Step-by-step explanation:

replace x with 2 then you get -1

Next step replace x with 5 then u get 5

Add 5 and -1. You get four.
