Answer:
y=2x-4
Step-by-step explanation:
If a line is parallel to another line, the only thing that's different in the equation is the y-intercept. Therefore we can solve for the y-intercept using the point (4,4)...
Note that the slope-intercept equation is y=mx+b where b is the y-intercept and m is the slope. x and y are the x and y coordinate pairs.
y=2x+b
4=2(4)+b
4=8+b
b=-4
Therefore the equation of the line that is parallel to y=2x+4 and passes through (4,4) is...
y=2x-4
Answer:
<h3>b. y=arcsinx</h3>
Step-by-step explanation:
Given the function y = sinx
The equation of its inverse can be gotten by first taking the arcsin of both sides as shown
arcsiny = arcsin(sinx)
The arcsin will cancel out the sin function at the right hand side to have;
arcsiny = x
x = arcsiny
Replacing the variable 'y' with x and 'x' in y in the resulting equation we have;
y = arcsinx
This gives the required inverse.
