Question

What is the value of f(-4)?

Answer 1

Given is a piecewise function which follows different expressions according the the value of input x.

Given $f(x)=\left \{ {{-10, \;if \;x2} } \right.$

It says to find f(-4) i.e. the value of function f(x) at x = -4.

At point x = -4, f(x) is x³, if -5 ≤ x ≤ 2.

So, f(-4) = (-4)³

f(-4) = -4 × -4 × -4

f(-4) = -64.

Hence, option A is correct i.e. -64.
