The function f(x) = 14.5 -0.25x2 is used to model the curve of a train tunnel, where x is the distance from the
center of the tunnel, and the x-axis represents the
ground. The mathematical range for the function is the
set of real numbers less than or equal to 14.5.
Which statement describes how the reasonable range differs from the mathematical range?

-6 is the correct option from the above given options

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
