Question

What is the value of f(x) when x = 4 in the piecewise function f(x) =

2x² when x>4 …….. 4x when x < 4

Answer 1

The question asks the value of f(x) when x = 4 in the equation

x = 4 is less than or equal to 4, so we use the first equation in the piecewise functions => {4x when x≤4}

Solving for f(x):

4(4)=16

16 is the answer!

Hope it helps!
