A function is given below. f(x) = x + 2
Which is a true statement about this function?
A
The output value of the function is 2 when the input value is 2.
B
The output value of the function is 3 when the input value is 1.
с
The output value of the function is 2 when the input value is 2.
D
The output value of the function is 1 when the input value is 3.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

step-by-step explanation:

the answer would be 7

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
