Evaluate this function at x=−7. Express your answer as an integer or simplified fraction. If the function is undefined at the given value, indicate "Undefined".
@lowkey
What do you think?
\[\frac{ 3 }{ 2}\]
Let me do my magic and check if it's right
okay
Not quite. How did you get to this answer?
\[\frac{ 1 }{ 2} (-7) + 5\]
Okay. So restrictions are basically the ones with the greater sign signs and the x. You follow?
I'm behind you so far
it's not the right answer ?
low ?
hellow! are you online? sorry i was afk.
So restrictions basically for the first equation is saying, for any number less than -3, use this formula. if your number is greater than or equal to -3, use the second formula. Now that we know this, which formula do we use to plug in -7?
yes
the first equation ?
and it's alright
Yes! so plug in -7 to first equation
\[-\frac{ 3 }{ 4}(-7) - 7 = -\frac{ 7 }{ 4}\]
