How do i do this question?

you find the square root of two and add it to 3.14. Then you find the square root of 5. after that you divide the top by the bottom and you have your answer

Step-by-step explanation:

The correct answer would be 2.0

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
