2. Without graphing, determine whether the function represents exponential growth or exponential decay. Then find the y-intercept.
y=12(17/10)^x
exponential growth: 1.7
exponential decay: 1.7
exponential growth: 12
exponential decay: 12

What are the domain and range of the function? f(x) = -4 (sqrt)x

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
