Question

If f(x) = 2 ( x - 5)
Find: f19)
:(

Answer 1

28

Step-by-step explanation:

All you have to do is to plug the number that is in parentheses -> f(x), in this case, is 19 therefore all you really had to do is to plug 19 into the equation and then solve.

Answer 2

After evaluating the expression:f(x)=2(x−5);f(19 we get, f(x)=2x−10;19f.

Let's evaluate the expression:

f(x)=2(x−5);f(19)

We can evaluate the expression by distributing the terms and re-ordering them so the constants are on the left.

Steps to solve:

1. Distribute:

f(x)=2x−10;f(19)

2. Re-order terms so constants are on the left:

f(x)=2x−10;19f

Answer:

f(x)=2x−10;19f
