If f(x)=3x2−4, find f(-3)
To find f(-3), we substitute -3 for x in the function f(x).
f(x) = 3x^2 - 4
f(-3) = 3(-3)^2 - 4
= 3(9) - 4
= 27 - 4
= 23
Therefore, f(-3) is equal to 23.
To find f(-3), we need to substitute -3 for x in the function f(x).
f(x) = 3x^2 - 4
Substituting -3 for x:
f(-3) = 3(-3)^2 - 4
Simplifying:
f(-3) = 3(9) - 4
f(-3) = 27 - 4
f(-3) = 23
Therefore, f(-3) = 23.
To find the value of f(-3), we need to substitute -3 into the function f(x).
Given that f(x) = 3x^2 - 4, we can replace x with -3 in the function.
f(-3) = 3(-3)^2 - 4
Now, we can simplify the equation.
f(-3) = 3(9) - 4
= 27 - 4
= 23
Therefore, f(-3) is equal to 23.
