7-6 Skills Practice Transformations Of Exponential Functions Answers -
It’s ( y = k ). Here, ( k = 1 ). So the asymptote is ( y = 1 ).
Parent: ( y = 2^x )
Here’s a guide to mastering the transformations of exponential functions, which is almost certainly what this worksheet covers. Every problem on that worksheet will likely start with the parent function: [ f(x) = b^x ] where ( b > 0 ) and ( b \neq 1 ). It’s ( y = k )
I understand you’re looking for answers to a specific math worksheet: “7-6 Skills Practice Transformations of Exponential Functions.” While I can’t provide a direct answer key (as those are typically copyrighted by publishers like McGraw-Hill or Pearson), I can certainly help you understand how to find the answers yourself by explaining the key concepts and walking through typical problems. Parent: ( y = 2^x ) Here’s a
Set ( x = 0 ): ( y = 3 \cdot 2^(0-4) + 1 = 3 \cdot 2^-4 + 1 = 3 \cdot \frac116 + 1 = \frac316 + 1 = 1.1875 ). (Without a calculator, leave as ( \frac1916 ) if needed.) Set ( x = 0 ): ( y
Set ( y = 0 ): ( 0 = 3 \cdot 2^(x-4) + 1 ) → ( -1 = 3 \cdot 2^(x-4) ) → ( -\frac13 = 2^(x-4) ). Since a positive base (2) to any power is always positive, there is no x-intercept .
Then, the transformed function will look like this: [ g(x) = a \cdot b^(x-h) + k ] | Parameter | Effect on the graph | How it changes the equation/points | | :--- | :--- | :--- | | a (Vertical stretch/shrink & reflection) | - If |a| > 1: vertical stretch - If 0 < |a| < 1: vertical shrink - If a is negative : reflection over x-axis | Multiply all y-values by a. The y-intercept changes from 1 to a. | | h (Horizontal shift) | - Right if h > 0 - Left if h < 0 | Replace x with (x – h). The horizontal asymptote does NOT change. | | k (Vertical shift) | - Up if k > 0 - Down if k < 0 | Add k to the whole function. The horizontal asymptote changes from y=0 to y=k. | | b (Base) | - If b > 1: growth (increasing) - If 0 < b < 1: decay (decreasing) | Changes the steepness but not the asymptote. | Step-by-Step to Find the Answer for Any Problem Let’s say a problem gives you: ( y = 3 \cdot 2^(x-4) + 1 )
