please answer it please please give me correct step wise explanation improper answer will be reported​

Answer 1

Step-by-step explanation:

-4 is less than 0

so,f (x)=x square

f (-4)=(-4)square

f(-4 )=16

$0 \leqslant x \leqslant 1$

$0 \leqslant 1 \leqslant 1$

so, f (1) = x

x=1

f (1)=1

f

$\sqrt{7}$

root 7>1

$so \: f( \sqrt{7)} = 1 \div x$

$f( \sqrt{7)} = 1 \div \sqrt{7}$

f (sqroot 7)=1/root7
