Answer:
f(-3) = 9
Step-by-step explanation:
Lets define f(a) first where a is any integer,
f(a) is found out by putting the integer in the function in place of the variable
So for the given question
[tex]f(x) = x^{2}[/tex]
In order to find f(-3) we will put -3 in place of x
So putting -3,
[tex]f(-3) = (-3)^{2}[/tex]
[tex]f(-3) = 9[/tex]
So, the value of function at -3 is 9 ..
Answer: [tex]f(-3)=9[/tex]
Step-by-step explanation:
Given the quadratic function [tex]f(x)=x^2[/tex], you can find [tex]f(-3)[/tex] by substituting the input value [tex]x=-3[/tex] into this function, with this procedure you will get the corresponding output value.
Therefore, when [tex]x=-3[/tex], you get that the output value is the following:
[tex]f(x)=x^2\\\f(-3)=(-3)^2[/tex]
NOTE: Since the exponent is an even number, the result will be positive, because:
[tex](-3)(-3)=3[/tex]
Therefore, knowing this, you get that [tex]f(-3)[/tex] of the function [tex]f(x)=x^{2}[/tex] is:
[tex]f(-3)=9[/tex]
