4) An exponential function has the following equation: y=2* a) Write the equation if it have been moved up 3.
b) Write the equation if it has been reflected
across the y-axis.
c) Write the equation if it has been moved
down 4 and has been vertically stretched
by a factor of 3.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

noncoplanar points are points that do not lie on the same line.

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)
