Let f(x)=8x. The graph of f(x) is transformed into the graph of g(x) by a vertical stretch of 4 and a translation of 7 units down. What is an equation for g(x)?
1 Answer
Answer:
Explanation:
In
•
#a# represents the vertical stretch•
#b# represents the horizontal stretch•
#c# represents the horizontal translation•
#d# represents the vertical translation
We are given that
Therefore, the equation of
#g(x) = 4(8x)  7 =32x  7#

Consider the function
#f(x) = x^3# .#f(x)# undergoes a vertical transformation of#5# units down and a horizontal translation of#2# units right. It is reflected over the xaxis. What is#f(x)# 's new equation?

The point
#(6, 4)# lies on the graph of function#g(x)# . What are the coordinates of the point that will lie on#2g(3x  9) + 1# ?
Solutions
#f(x) = (x  2)^3 + 2# #(5, 7)#
Hopefully this helps!
