Question

Which is the correct input-output table for the function f(x) = 7 – 4.5x?

Answer 1

Okay so input would be at 1 and the output at 2.5, making the answer B.(If you're on plato) :D

Answer 2

Answer:

The function is given to be :

f(x) = 7 - 4.5x

Now, to make a correct input-output table for the given function write the given function in the form of y and x

⇒ y = 7 - 4.5x

Now, in this equation x is independent variable and y  is dependent variable.

So, give the input values to the variable x and note down the output values of variable y.

The required table is :

x      0         1           2             3

y      7        2.5       -2           -6.5
