f(x) = 2x - 14
Find f(3) and f(-3).
f(3)=2 -14=7
f(3)=2+14 is this correct
substitute the x with 3 for the first question..
you'll get f(3)=2(3)-14
f(3)=6-14
f(3)=-8
solve the second one by substituting x with -3...
thank you again
you're welcome again.. =)
No, your calculation for f(3) is not correct. Let me explain how to find the correct value for f(3).
To find f(3), we need to substitute 3 into the function f(x) = 2x - 14.
So, plugging in x = 3 into the function, we have:
f(3) = 2(3) - 14
Now, we can simplify the expression:
f(3) = 6 - 14
Finally, we can calculate the result:
f(3) = -8
Therefore, the correct value for f(3) is -8.
Similarly, to find f(-3), we substitute -3 into the function:
f(-3) = 2(-3) - 14
Again, we simplify the expression:
f(-3) = -6 - 14
And calculate the result:
f(-3) = -20
So, the correct value for f(-3) is -20.
