You will need to rent a computer and the cost will be $30 down and $15 a day. You sign a contract and you must pay the $30 down whether you rent the computer or not. Is this a linear function? Explain. What is the rate of change? What is the practical meaning (in context of the problem) of the rate of change? What is the vertical intercept? What is the practical meaning of the vertical intercept? Write the equation using function notation. What is the practical domain of the function? What is the practical range of the function?

MULTIPLE CHOICE If f(-5) = 2 and f(1) = 14, what is the slope-intercept form of the linear function f? First: Determine the ordered pairs: (-5,2) and (1, 14) V₂-V1 14-2 Second: Find the slope by using *₂-₁1-(-5) m = ? Third: Write in Point-Slope form: YY₁ = = m(x -x₁) y Fourth: Write in Slope-Intercept Form by solving for y Remember: 0,0 Be sure to answer Problem D in your Lesson Companion. A B f(x)=-3x-17 f(x)=2x-9 1) y-14 = 2(x-1) с f(x)=2x+12 * Practice
