limit x mendekati 3 - akar x pangkat 2 + 5 / 4 - x pangkat 2

langsung aja y

lim -√x² + 5 / 4-x²
x→3

= -√3²+5 / 4 - 3²
= -√9+5 / 4 - 9
= - √14 / -5
= √14 / 5

semoga berguna +_+

Lim (3 - √(x^2 + 5)) / (4 - x^2)
= Lim (3 - √(x^2 + 5)) / (4 - x^2) . (3 + √(x^2 + 5))/(3 + √(x^2 + 5))
= Lim (9 - (x^2 + 5)) / (4 - x^2)(3 + √(x^2 + 5))
= Lim (4 - x^2) / (4 - x^2)(3 + √(x^2 + 5))
= Lim 1/(3 + √(x^2 + 5))
= 1/(3 + √(2^2 + 5))
= 1/(3 + √9)
= 1/6
