Question

. Determine f(4.5) for the function f(x) = 3x - 5 *

Answer 1

Algebra

f(4.5)=8.5

Plug in x as 4.5 and multiply it with 3. Then subtract 5 from the remaining result.

Answer 2

Answer:

f(4.5) = 8.5

Step-by-step explanation:

f(4.5) = 3x - 5

f(4.5) = 3(4.5) - 5

f(4.5) = 13.5 - 5

f(4.5) = 8.5

Hope that helped! You have to substitute x with 4.5 and then solve.
