Question

Graph of f(x) is given. Find the graph of $f\left(x\right)-2$

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

When we are doing the transformation y = f(x) $\mp$ a units along y-axis.Only value of y changes by a.In our case, we want to do the transformation $f\left(x\right)-2$. For this, the graph moves down by 2 units.
We can verify this for $x=2.f\left(2\right)=0$ (from the graph given). The new function, $f\left(x\right)-2=0$, when $x=0$.

$\Rightarrow$ option C
