PLEASEE HURRYY Determine if the given function has any points of discontinuity. Explain your reasoning.
f(x) = x² – b²/x-b
a
O There is a point of discontinuity at x = b because the denominator has the factor x - b.
O There are points of discontinuity at both x = -b and x = b because the numerator has factors of x + b and X - 6.
There is a point of discontinuity at x = -b only because the factor of x - b is common to both the numerator and
denominator
There is a point of discontinuity at x = b only because the factor of x - b is common to both the numerator and
denominator and factors out.

john got lost so he didn't know what to do and it was crazy because he didn't except it

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
