Question

F(x)=((×))= {{x}}" align="absmiddle" class="latex-formula">

Answer 1

Let y = f(x),
y = x
For every unit that y increases, x increases by 1 unit. The straight line graph will cut the y-axis at the origin (x = 0 & y = 0), and form 45° with both x-axis and y-axis at the original.

Hope this helps!
