(Alg 1B) Exponential Function Review

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

• Slope (rate of change)

• Common multiplier

• Initial Value (y-intercept)

• Input

What is the pattern you see in this table?

• repeated multiplication by 1/3

• repeated addition by 8

• repeated multiplication by 3

• repeated division by 3

What is the equation for the table?

• y = 4(3)^x

• y = 36(4)^x

• y = 108(3)^x

• y = 36(3)^x

This is the horizontal line which the values of the function cannot fall below :

• Asymptote

• Growth Factor

• Axis of symmetry

• Curve

Which of the following functions shows an initial amount of $15 and an increase of 35% each year?

Use the formula y=a(1+r)^x

• y = 15(35)^x

• y = 15(1.35)^x

• y = 15(0.35)^x

• y = 35(1.15)^x

Use the formula y=a(1-r)^x

• ^.08

• ^1.08

• .92

• 8
