Jessica has saved $5. She doubles the amount she saves each week. Does this represent an exponential function?

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
