f(x) = - 3x ^ 2 + 10x + 2 Find f(- 6)
f(x) = - 3x ^ 2 + 10x + 2
f(-6) = ....
wherever you see an x , replace it with -6
To find the value of f(-6), we need to substitute -6 into the given function and calculate the result. Let's go step by step:
Step 1: Write down the function:
f(x) = -3x^2 + 10x + 2
Step 2: Substitute -6 into the function in place of 'x':
f(-6) = -3(-6)^2 + 10(-6) + 2
Step 3: Simplify the equation following the order of operations (PEMDAS/BODMAS):
f(-6) = -3(36) + (-60) + 2
= -108 - 60 + 2
= -166 + 2
= -164
Therefore, f(-6) = -164.
To find f(-6), we need to substitute -6 into the equation given:
f(x) = -3x^2 + 10x + 2
Now, replace x with -6:
f(-6) = -3(-6)^2 + 10(-6) + 2
Next, simplify the equation:
f(-6) = -3(36) - 60 + 2
= -108 - 60 + 2
= -166 + 2
= -164
Therefore, f(-6) = -164.
