An inverse function produces points (y,x) for every point (x,y) produced by the parent function. So to find the inverse function, you solve for the independent variable and when done switch the variable labels....
y=x+5 subtract 5 from both sides
y-5=x now switch labels
y=x-5
So if f(x)=x+5
f^-1(x)=x-5

Answer: Elisa
Step-by-step explanation:
Since Elisa withdrew $23 at a time from her bank account and withdrew a total of $207, the number of times that Elisa withdrew will be:
= $207/$23
= 9 times
Since Frances withdrew $43 at a time from his bank account and withdrew a total of $172, the number of times that Frances withdrew will be:
= $172/$43
= 4 times.
Based on the calculations, we can see that Elisa made the greater number of withdrawal.
Answer:
d) the slope of f(x) is greater than the slope of g(x)
Step-by-step explanation:
to find the slope of an equation, you look at its rise/run. for f(x), you can see that from one point (0, 3) to another (1, 1) it goes down 2 values (3 - 1) and over 1 value (0 + 1). because it goes down 2 values, the rise is -2, and because it moves to the side 1 value positively, the run is +1.
-2/+1 = -2. this means the slope of f(x) = -2.
finally, it says the slope of g(x) = -6, and -2 > -6. i hope this helps! :)
30.63 for 3 sets of pencils......that means each set cost (30.63 / 3) =
10.21....so the change in his account for 1 set of pencils is -$ 10.21 <=
