Answer:
(-2,1)
Step-by-step explanation:
So we are given f(-3)=1 since the point (-3,1) is on f(x).
We want to use this point to find a point on f(x-1).
Now,
f(-3)=1
and we want
f(x-1)=1
What would x need to be such that x-1 is -3.
x-1=-3
Add 1 on both sides:
x=-3+1
x=-2
x would need to be -2 in f(x-1)=1 in order to use that f(-3)=1.
So (-2,1) is the point for the function f(x-1) that corresponds to the point (-3,1) for f(x).
I know that f(x-1) would only be effecting our input because x-1 is the input.
Answer:
Use y + x = 3 and solve for either x or y.
Step-by-step explanation:
Substitution is a method to solve a system of equations by substituting an expression from one equation into the other.
To begin, first solve one equation by isolating for one variable. Choose the equation which will have the least number of steps to do so.
y + x = 3 can be solve for x or y by subtracting the other variable. Since this only requires one step use this equation. Either variable can be used.
