Answer:
He set the factored expressions equal to each other. instead of setting them equal to zero
Step-by-step explanation:
f(x) = x^2 + 4x + 3. His work is shown below.
0 = x^2 + 4x + 3
0 = (x + 3)(x + 1)
Here is where we use the zero product property
x+3 = 0 x+1 =0 We do not set them equal to each other
Answer:
(-3,-4)
Step-by-step explanation:
When reflecting across the y-axis, you will mirror the coordinates across the y-axis. This means (5,-4) will turn into (-5,-4) because mirroring it across the y-axis will only change the x coordinate. Then, to translate it to the right, you move to the right two times to give you (-3,-4). The y-coordinate will never change in this situation because you are only reflecting and moving left and right.
