Ms. Walker's class set up an online 5(2)^x = 1,280; x = 8
fund with a goal to raise $1,280 to
go on a field trip. Ms.Walker starts
the fund by depositing $5. Each
week the balance of the fund is
twice the balance of the previous
week. Which equation can be used
to find the number of weeks, x, after
which the balance of the fund will
reach 1,280, and how many weeks
will it take to reach the class goal?
Sam purchased a new car for WRONG - 17,930 (0.81)^x _< 1900
$17,930. The value of the car
depreciated by 19% per year.
Which expressions are equivalent to log10(20x^5) - 1, log10 (10x)
the given expression.
, Match each logarithmic equation to log5x=4 —> 625
its corresponding x-value log4x=2 —> 16
log10x=3 —> 1,000
log2x=5 —> 32
What value of x satisfies this 0.75
equation? 1.5(4)^2x = 12
What is the approximate solution to x ≈ 148.4
this equation? 4Inx - 8 = 12
If function f is the parent g(x) = 3f(x)
exponential function f(x) = e^x.
What is the equation of transformed
function g in terms
Consider the graph of the function (- infinity, 1)
f(x) = 10^x, what is the range of
function g if g(x) = -2f(x) + 1
Which statements are true about PARTIALLY WRONG - The graph has a range of
the graph of function f? {y| - infinity < x < infinity} and decreases as x
approaches 0
(this is correct but it's not the only answer)
Consider the graph of the function j(x) = f(x) -1/2 —> vertical asymptote of x = 0
f(x) = In x, match each h(x) = f(x - 1/2) —> y-intercept at (0,-1/2) WRONG
transformation of function f with a (should be x-intercept at (1.5,0) by default but idk)
feature of the transformed function. g(x) = -1/2f(x - 2) —> function decreases as x
increases
