## Initial value rate of change

24 Jul 2018 How to Write an Exponential Function Given a Rate and an Initial Value. Exponential functions can model the rate of change of many situations,

the effect of changing the initial value on the graph of an exponential function Recall also that the average rate of change of a linear function is constant. Identify the percent rate of change. a. y = 5(1.07)t b. f(t) = 0.2(0.98)t 3. Solve the Problem a. The initial value is \$21,500, and the rate of decay is 12%, or 0.12. 24 Jul 2018 How to Write an Exponential Function Given a Rate and an Initial Value. Exponential functions can model the rate of change of many situations,  Slope: Very often, linear-equation word problems deal with changes over the course of time; the With what initial velocity was the ball thrown? always work this way: the slope is the rate of change, and the y-intercept is the starting value. x0 is the initial value at time t=0. r is the growth rate when r>0 or decay rate when r<0, in percent. t is the time in discrete intervals and selected time units. It is the value of the dependent variable when x = 0. b is the coefficient of the independent variable. It is also known as the slope and gives the rate of change of  For example, we may ask: What is the value of the function at x = x0? This question asks: "For this particular value

### To write an exponential function given a rate and an initial value, start by determining the initial value and the rate of interest. For example if a bank account was opened with \$1000 at an annual interest rate of 3%, the initial value is 1000 and the rate is .03.

This assignment has students determine the rate of change and initial value of linear functions from multiple representations. Students are given tables, graphs, equations, and verbal descriptions in which they must find the rate of change and the initial value. A key is included. This is the perfec MFM1P Math Task Template Check out this Math Task Template to get some practice in 5.7 – Initial Value and Rate of Change of the grade 9 applied math course. This assignment has students determine the rate of change and initial value of linear functions from multiple representations. Students are given tables, graphs, equations, and verbal descriptions in which they must find the rate of change and the initial value. NOTES: Lesson 4-14: Comparing Rate of Change & Initial Value 1.) Angela and Ben each have a monthly cell phone bill. Angela’s monthly cell phone bill is represented by the graph below. Ben’s monthly cell phone bill is represented by the equation y=0.15x+49, where x represents the number of minutes and y represents the monthly cost.
