Exponential Functions A and B Values

Given the original exponential function defined by y=4^x, how would the graph change if the function were: y=2(4)^x-3+1?

• Vertically stretched by a factor of 2, right 3, and up 1

• Vertically compressed by a factor of 1/2, left 3 and down 1

• Vertically compressed by a factor of 1/2, right 3, and down 1

• Vertically stretched by a factor of 2, left 3, and up 1

Which function represents the table of values?

• f(x) = 4x

• f(x) = x⁴

• f(x) = 4^x

• f(x) = 4^x-1

Does this table represent exponential growth or decay?

• Growth

• Decay

Determine if the table represents linear or Exponential Function.

• Linear

• Exponential

• Neither

In an exponential function, what does the 'a' represent?

• Y-INTERCEPT (also the initial amount)

• GROWTH OR DECAY FACTOR

In an exponential function, what does the 'b' represent?

• Y-INTERCEPT (also the initial amount)

• GROWTH OR DECAY FACTOR

What is the initial amount, for the function: f(x) = 300(1.16)^x?

• 300

• 1.16

• .16

• x

If y = ab^x represents an exponential growth function, what are the possible values of b?

• b = 1

• b > 1

• b < 0

• 0 < b < 1
