Answer:
x^2 - 4
Step-by-step explanation:
Number squared (x)^2
less than is a subtraction term
put them together you get x^2 - 4
X^2-4
Let x be our number.
So we square the number because it says 4 less than the square number.
So we have x^2.
Now, we have to take 4 less than that.
So x^2-4 is our answer.
(This can also be factored because it is in the form a^2-b^2)
(This can be rewritten as (x+2)(x-2))
6 packs
you add $4.00 and $2.50 together, and get 6.50 and then divide 39 bye $6.50
The answer is 1400
f(3) = - 9
To evaluate f(3) , substitute x = 3 into f(x) , that is
f(3) = - (3)² = - 9
C, hope this helps :)
