y = A(Bx - C)ⁿ + D
A is a vertical stretch (or shrink if |A| < 1)
B is a vertical shrink (or stretch if |B| < 1)
C is a shift to the right (or left if C is negative) → notice that Bx - C is "-C" so to take the opposite
D is a shift up (or down if D is negative)
when C = -3, it is a shift to the left 3 units
when D = -7, it is a shift down 7 units
Answer: B
Answer:
Lisa is 5 years old
Step-by-step explanation:
we can make an equation like
4x=15+x
X can represent Lisa’s current age
Now just solve for X
3x=15
x=5
And we can check
If Lisa is 5 years old now
In 15 years she would be 20
And 20 is 4 times as 5 which Is her current age
So Lisa is 5 years old now.
