Question

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

Answer 1

Answer:

The output for x = 2 is

$\therefore f(2)=9$

Step-by-step 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

$f(2)=2(2)^{2}-3(2)+7= 2\times 4 -6 +7 = 8+1=9$

The output for x = 2 is

$\therefore f(2)=9$
