g(2) means plug in x = 2 into the function g(x) = |-2x + 4| and f(-1) means plug x = -1 into f(x) = 3x - 1.
That will give you two numbers that you can then use to calculate g(2) - f(-1)
6.43125...
To the nearest cent, I'm assuming they mean, 6.43, since there is no 5 or higher number in the thousandths place...
Answer:
3 units
Step-by-step explanation:
∠A = ∠E (same arc BD)
∠X share
ΔXDA similar to ΔXBE
XE / XA = XB / XD
(3 + DE) / 9 = 2 / 3
9 + 3DE = 18
3DE = 9
DE = 3
What you should know for this case is that all quadratic functions represent a parabola.
We have then that the function with vertice (-2, 0) is:
y = (x-2) ^ 2
Notice that if you substitute the value x = -2 in the equation then y = 0
Answer:
y = (x-2) ^ 2
