Answer:
x+11.5
Step-by-step explanation:
4x² +7x-2=0
16x+7x-2=0
23x-2=0
+2 +2
23x=2
23x/2
x= 11.5
I hope these help.
Answer:
y = 3f(-1/5x + 1/5)
The function is
- vertical stretched by a factor of 3
- reflected across y-axis
- horizontal stretched by a factor of 5
- horizontal translated to the left 1/5 units
Step-by-step explanation:
Starting with: y = f(x)
Replacing x with -1/5x: y = f(-1/5x)
Replacing x with x - 1: y = f(-1/5(x - 1)) = f(-1/5x + 1/5)
Replacing y with 1/3y: 1/3y = f(-1/5x + 1/5) or y = 3f(-1/5x + 1/5)
The transformation:
- kf(x) vertically stretches the function by a factor of k (here k is 3)
- f(-x) reflects the function across y-axis
- f(bx) horizontally stretches the function by a factor of 1/b (here b is 1/5)
- f(x + c) horizontally translates the function left c units (here c is 1/5 units)
