Answer:

Step-by-step explanation:

F(x) =2 when x^2-3

(2)^2-3=4-3=1

Use the substitution method

F(-2)=x^2-3

=(-2)^2-3

Use PEMDAS

P= parenthesis

E= exponents

M=multiplication

D=division

A=addition

S=subtraction

Do (-2)^2 first then -3

Put down (-2)(-2) two times because of the exponent

-negative number * -negative number= +positive number

4-3

=1
