(a) Find the output of the function y=5x-7 when the input is 4


Inputs
x=4

Y=5x-7

Y=?

Outputs


(b) Find the function when the input is -1
What about for input of 1?










(c) Find the input of the function that would produce an output of -17.

Answer 1

a) We are given a function

y = 5x - 7

when x = 4, then

y = 5 (4) - 7

y = 13

b)  When the input is -1,

y = 5x - 7

y = 5 (-1) - 7

y = -5 - 7

y = - 13

And, when input is 1

y = 5x - 7

y = 5(1) - 7

y = 5 - 7

y = -2

c) To produce the output -17, the input of the function will be,

-17 = 5x - 7

-17 + 7 = 5x

-10 = 5x

x = -2

Therefore, the input of the function must be -2 to get the output -17

What is the meaning of a function?

• Function in mathematics is a relation between the inputs and the possible outputs.
• In function, each input is related to the one output.
• The representation of function is y= f(x).
