Afunction f(x) has x-intercepts of –3 and –5. what is the constant term in the function? f(x) = x2 + 8x +

15

Step-by-step explanation:

since the x-intercepts are x = - 3 and x = - 5 then the factors are

(x + 3) and (x + 5), hence

f(x) = a(x + 3)(x + 5) ← a is a multiplier

let a = 1 then

f(x) = (x + 3)(x + 5) ← expand factors

f(x) = x² + 8x + 15 ← 15 is the constant term

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
