Find the solutions to the system of equations. Select all that apply. Y=x^2-1 y=2x-2
Sliva [168]

Answer:

Option C (1, 0)

Step-by-step explanation:

We have a system with the following equations:

y = x ^ 2-1\\\\y = 2x-2

The first equation is a parabola.

The second equation is a straight line

To solve the system, substitute the second equation in the first and solve for x.

2x-2 = x ^ 2 -1

Simplify

x ^ 2-2x + 1 = 0

You must search for two numbers that when you add them, obtain as a result -2 and multiplying both results in 1.

These numbers are -1 and -1

Therefore

x ^ 2-2x + 1= (x-1)(x-1)\\\\x ^ 2-2x + 1= (x-1)^2=0

Finally the solutions are

x = 1\\y =0

Select the correct answer. Consider the function f(x) = x2 and the function g(x) shown below. How will the graph of g(x) differ
katen-ka-za [31]

Answer:

B

Step-by-step explanation:

just think logically about it.

you take f(x) (which stands for the result value y, you know that), do not change f(x) in any way but add finally 5 to every y value created.

there is no other effect than moving the whole f(x) curve up by 5 units, because every y value is now bigger by 5 units.
