Answer:
He didn't calculate the b-value correctly.
Step-by-step explanation:
The given parent function is:
The transformation is of the form:
The period is given by
If we want the new function to have a period of
Then we solve the following equation for b.
will translate the graph horizontally to the right by
units.
+d shifts the graph up by d units.
The new function then becomes:
Answer:
y = -3x - 19
Step-by-step explanation:
The line passes trough (-6,-1)
The line is parallel to line whose equation is 3x + y = -7
Writing the equation of this parallel line in slope intercept form:
y = -3x - 7
Because the two lines are parallel, their slopes are the same.
Since the slope(m) is -3, equation of our first line will be:
Slope(m) = Change in y ÷ change in x
Taking another point (x,y) lying on our first line:
-3 = =
Cross multiplying gives;
y + 1 = -3x - 18
y = -3x - 19
