4) An exponential function has the following equation: y=2* a) Write the equation if it have been moved up 3.
b) Write the equation if it has been reflected
across the y-axis.
c) Write the equation if it has been moved
down 4 and has been vertically stretched
by a factor of 3.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
