Identify the initial amount $a$a and the rate of growth $r$r (as a percent) of the exponential function $y=350\left(1+0.75\right)^t$y=350(1 +0.75)t . Evaluate the function when t is equal to 5$t=5$t=5

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 4x^2 - 19x- 5
