Our parent function is f(x)=x^2. A vertical stretch by a factor of k means that every point (x,f(x)), has been transformed into (x,kf(x)). Alex is clearly incorrect as our parent function has been transformed to (x,9f(x)), not (x,3f(x)). A horizontal stretch(or compression) by a factor of k means our function has been transformed to (x/k,f(x)). Here, Marta is saying our function should look like (3x,f(x)). This can also be achieved by plugging 3x into the parent function, which would give us f(3x)=(3x)^2, so it seems that Marta is the correct one.
The first thing thing you must do is create an equation for this problem. Remembering that 7.75% = 0.0775
($4,100 × 0.0775 + $4,100 ) + $600
Now, all you have to do is solve it. You will first have to start with the numbers in the parenthesis using the order of operation (PEMDAS).
P = Parenthesis
E = Exponent
M = Multiplication
D = Division
A = Addition
S = Subrtaction
$4,100 × 0.0775 + $4,100 ) + $600
$4,417. 75 + $4,100 + $600
$4,417. 75 + $600 = $5,017.75
Danielle made $5,017. 17 last week.
I hope this helps! :)
