# Logarithms and Exponential Functions: EXPO Construction Kit Quiz

Think you’ve got your head wrapped around Logarithms and Exponential Functions? Put your knowledge to the test. Good luck — the Stickman is counting on you!
Q. Find the function that doubles in value for every interval and passes through (3, 24).

y = 3(8x)
y = 3(2x)
y = 2(3x)
y = 8(24x)
Q. Find a function that decreases by 3 for every interval and passes through (1, 5).

y = 3x – 5
y = 8x – 3
y = -x + 8
y = -3x + 8
y = x-3 + 8
Q. Find the exponential function that passes through (0, 2) and (2, 98).

y = 2(7x)
y = 7(2x)
y = 14(2x)
y = 49(2x)
y = 2(14x)
Q. Find the exponential function that passes through (1, -6) and (2, -18).

y = 2(3x)
y = -6(3x)
y = 2(-3)x
y = -2(3x)
y = 6(-2x)
Q. Rewrite y = 4e2x in logarithmic form.

Q. Rewrite y = -4(55x + 1) in logarithmic form.

Q. Rewrite y = log7(10x2) in exponential form.

Q. Rewrite y = ln(10ex) in exponential form.
