Answer :
Final answer:
The value of (f of)(z) is 2z².
Explanation:
The function f(x) = 2x² means that whatever value of x is given, it needs to be squared and then multiplied by 2. So to find the value of (f of)(z), we substitute the value of z into the function f(x) = 2x²:
f(z) = 2z²
Therefore, the value of (f of)(z) is 2z².
