f(x) = 6^x-7 if x < 8
log2 x + 3 if x > 8
Step 1 of 3: Evaluate this function at x = 16. Write the exact answer. Do not round. If the answer is
undefined, write Und as your answer.

Step 1

Since x = 16, which is greater than 8, we will use the function f(x) = log_(2)x + 3. Show more…

Thanks for your feedback!

f(x)={(6^(x-7) if x<8),(log_(2)x+3 if x>8):} Step 1 of 3: Evaluate this function at x=16. Write the exact answer. Do not round. If the answer is undefined, write Und as your answer. ifx<8 1ogx+3if x> 8 Step 1 of3:Evaluate this function atx = 16.Write the exact answer.Do not round.If the answer is undefined,write Und as your answer.
