Answer:
Therefore,
[tex]f(-2)=-11\\f(0)=5[/tex]
Step-by-step explanation:
Function:
A function is like a machine that gives an output for a given input.
A function has an independent variable which is called the input of the function.
The output for a given input is called the dependent variable.
Here. 'z' is the input independent variable
f(z) is the function dependent variable i.e function of z as an output.
Here,
[tex]f(z)=5-4z^{2}[/tex]
Therefore, at z = -2 we have
[tex]f(-2)=5-4(-2)^{2}=5-4(4)=5-16=-11\\\\f(-2)=-11[/tex]
Similarly at z =0 we have
[tex]f(0)=5-4(0)^{2}=5-0=5\\f(0)=5[/tex]
Therefore,
[tex]f(-2)=-11\\f(0)=5[/tex]
