Answer:
f(5) does not equal 13.
Step-by-step explanation:
When we are given a function f(x), we can substitute any value for x as long as we change that value in the equation as well.
Therefore, if we are given f(5), we changed the x. Therefore, we also change the x in the rest of the equation. This would leave us with f(5) = 5² + 3. Now, we can just simplify.
f(5) = 5² + 3
f(5) = 25 + 3
f(5) = 28
Because we are asked to find if f(5) is equal to 13, we can see that 28 is definitely not equal to 13 and determine that this statement is false.
The word “of” automatically mean multiplication. So start by making 7 3/4 into an improper fraction: 31/4. Then multiple 3/4 by 31/4. You should get 93/20, or 4 13/20.
D because of the vertical line test. The c input 2 has two different out puts meaning that it is not a function
