Exponential functions are curves which approach a horizontal asymptote usually at y=0 or the x-axis. This function has been moved up 5 units so its asymptote is at y=5. This means the function never goes below 5 in its y-values.
The x values are not affected and all are in the function. This is the domain. So the domain is (-∞, ∞).
The y values are affected and are y > 5. This is the range and it is written
You will first add all the students the mentioned which gives you 13 then since they ask what is the probability it the teacher would pick girls. You know there's 10 girls and 3 boys so it would be 10/13.
Interest accumulates whether he pays or not. If he does not pay, the principal is not reduced, therefore the accumulated amount in 15 months is equal to Future value = 13000(1+0.036/12)^15 =$13597.45 (to the nearest cent)
