Question

Which exponential function goes through the points (1, 32) and (4, 2048)?

f(x) = 4(4)x

f(x) = 8(2)-x

f(x) = 8(4)x

f(x) = 4(4)-x

Answer 1

check which ones works
for example
\[f(x)=4\times 4^x\] does not work becaues \[f(1)=4\times 4^2=16\] not \(32\) as required

Answer 2

so no, not A

Answer 3

the answer is a
