Question

Iiana started to evaluate the function f(x)=2x^2-3x+7 for theinput value 2

Answer 1

The output for x = 2 is

`\therefore f(2)=9`

Explanation:

Function:

A function is like a machine that gives an output for a given input.

A function has an independent variable which is called the input of the function.

The output for a given input is called the dependent variable.

Here. 'x' independent variable

f(x) is the function dependent variable

`f(x)=2x^(2)-3x+7`

So Put x = 2 in the f(x) we get

`f(2)=2(2)^(2)-3(2)+7= 2* 4 -6 +7 = 8+1=9`

The output for x = 2 is

`\therefore f(2)=9`
