According to the data given in the question,** f(x) = 4(x + 2)**

We have to find out the value of **f(3).**

∴ Substituting, * x=3* in the equation for

*, we get,*

**f(x)**

**f(3) = 4(3 + 2)**

**∴ f(3) = 4(5) = 20**

**Hence, f(3) = 20**Hence, the correct answer is option

*.*

**a**Hope you are now clear. Ask your questions for more help.
