suppose we want to find lim(x→4) (x² + 3x - 28)/(x² - 11x + 28). if x = 4, the numerator is and the denominator is. question help: video submit part
Answer
Explanation:
Step1: Calculate numerator value
Substitute $x = 4$ into $x^{2}+3x - 28$. $4^{2}+3\times4 - 28=16 + 12-28=0$
Step2: Calculate denominator value
Substitute $x = 4$ into $x^{2}-11x + 28$. $4^{2}-11\times4 + 28=16-44 + 28=0$
Answer:
Numerator: 0, Denominator: 0
