Answer:
C
Step-by-step explanation:
The VLT is true if every x value has exactly 1 y value, which is true only in answer c.
The two functions are
y= f(x), ------------(1)
g(x)= f(x+2)---------(2)
⇒Consider a point (a,b) on the curve.It will satisfy (1).
b = f(a)
Now the point a is translated by 2 units right in horizontal direction and there is no vertical shift.
Coordinate of new point = (a+2,b)
Putting the value of new coordinate in equation (1), we get
b = f(a+2)
which gives equation (2), which is
g(x)= f(x+2)
Option (3) is correct,which is, the graph of g(x) is graph of f(x) translated 2 units right.
Answer: D
Step-by-step explanation:Lets label hot dogs as 'h' and soft drinks as 's'
6h + 4s = 13 (Equation 1)
3h + 4s = 8.50 (Equation 2)
We can solve by process of elimination.
Subtract equation 1 from equation 2.
We get:
3h = 4.5
h = 1.5
So that means that the hot dog costs $1.50 which is answer choice D.
