The loudness, L, measured in decibels (Db), of a sound intensity, I measured in watts per square meter, is defined as
L-1010g, where lo = 10-12 and is the least intense sound a human ear can hear. What is the approximate loudness of a rock
concert with a sound intensity of 10-17

O 2 Db
O 22 Db
O 60 Db
O 110 Db

Which graph corresponds to the function f(x) = x2 + 4x – 1?

Pranza plotted point a in the coordinate plane below.

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)
