1. Determine whether the graph of y = 3 + x2 is symmetric with respect to
the x-axis, the y-axis, or the origin.
2. A salesperson earns a base salary of $2,000 per month and a commission
of 5% on the amount of sales made. If the salesperson has a paycheck of
$3,006 for one month, what was the amount of sales for the month?
Solution: (correct?)
2,000 + .05(x) = 3006
2000 + .05(x) -2000 = 3006 - 2000
.05x = 1006
.05x / .05 = 1006 / .05
X = 20,120
The salesperson had $20,120 in sales for the month.
(2000+.05(20,120) = 3,006
3. For x values in what interval (s) is the function increasing?
4. a. Given f (x) = 4/x2 and g(x) = 3 - 2x, find the composite function
(f o g)(x) and simplify.
b. Write the equation for a function that has a graph with the
given characteristics.
The shape of y = |x| but stretched vertically by a factor of 2 and shifted right 3 units.
5. a. Solve for n: 2(n - 1) = 3(n + 5)
Solution:
b. Find the zero of the function f(x) = 8 - 2x

1. Determine whether the graph of y = 3 + x2 is symmetric with respect to
the x-axis, the y-axis, or the origin.
Since y=(x-0)^2+3,
the graph is symmetric with respect to the y axis.
2. A salesperson earns a base salary of $2,000 per month and a commission
of 5% on the amount of sales made. If the ...
