An exponential function is in the form of
You are watching: Which graph represents the function f(x) = |x| – 4?
Given: The role f(x) = y =
The domain is all actual numbers and the selection is y > 0.
y-intercept identified as the graph crosses the y-axis.
Substitute the worth of x= 0 in <1> to fix for y;
y-intercept = (0, 4)
when b =3 >1
therefore, the only graph which to represent the function y =
Hello native MrBillDoesMath!
Given: measure up angle STQ = 7x + 55. But, as shown, STQ is a right angle so
7x + 55 = 90 => subtract 55 from every side
7x = 90 -55 = 35 => division each next by 7
x = 35/7 = 5
Since RS = (x+1) + (2x-1) where x = 5.
RS = (5 + 1) + (2*5 -1)
= 6 + 9
I don"t know what selection the 4476mountvernon.com is as your diagram only shows choice A
A blood sample has 50,000 bacteria present. A drug fights the bacteria such the every hour the variety of bacteria remaining, r(
Let r(0) it is in the initial amount of bacteria. Every hour, r(n) reduce by half. So, ~ one our brand-new value for r(n) = (1/2)r(0). After 2 hours, r(n") = (1/2)r(n) = (1/2)(1/2)r(0) = (1/2)²r(0).

After n hours, r(n) = (1/2)ⁿr(0)
So as soon as n = 4 hours and also r(0) = 50,000, then
r(4) = (1/2)⁴r(0)
r(4) = (1/2)⁴ × 50,000
r(4) = (1/16) × 50,000
r(4) = 3125
So, after ~ 4 hours, we have 3125 bacteria present.
