-5/13
Formula: Y2-Y1/X2-X1
In division, exponents with the same base are subtracted.
example:
700/12 equals 58 and 1/3.
Answer:
see explanation
Step-by-step explanation:
Since p(x) = x² + 2 , if x ≤ 4
For x = 4 then this is included in the inequality x ≤ 4
whereas x > 4 does not include x = 4 but values greater than 4
Thus to evaluate x = 4 use p(x) = x² + 2
