Question

please answer the question in the picture below!

Answer 1

Given :-

• A graph of function is given to us .

To find :-

• The value of f(2) .

Solution :-

As we can see that the given graph passes through (1,0) and (0,-1) . So the slope of the line will be 1 . Also

$\red{\longrightarrow}$ y intercept = -1 .

On using the slope intercept form of the line ,

$\red{\longrightarrow}$ y = mx + c

$\red{\longrightarrow}$ y = 1(x) + (-1)

$\red{\longrightarrow}$ y = x - 1

or

$\red{\longrightarrow}$ f(x) = x - 1

On substituting x = 2 ,

$\red{\longrightarrow}$ f(2) = 2 - 1

$\red{\longrightarrow}$ f(2) = 1

Hence the required answer is 1.

Answer 2

i think it’s 1 not sure tho
