What is the value of x ?
3
4
6
8

x = 4

Step-by-step explanation:

10+2x = 18

2x = 8

x = 4

if you need y:

2y+4 = 10

2y=6

y=3

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
