Answer:
the equation of g(x) is,
Step-by-step explanation:
The transformation of the function is defined as:

where, b represents the horizontal shift.
if b> 0 then, the function f(x) shifts b units left and if b< 0 ; then the function shifts b units right
As per the statement:
The function f(x)=2x−5 is a linear function.
It is given that:
g(x) represent f(x) after a horizontal translation 3 units to the right.
⇒
then

⇒
⇒
Therefore, the equation of g(x) is, 
Answer is in The picture attached. Hope it helps!
Group and factor
group y's with y's and z's with z's
(y²-10y)+(10z-yz)
factor
y(y-10)+z(10-y)
force undistribute -1
-y(10-y)+z(10-y)
factor
(10-y)(-y+z)
(z-y)(10-y) or
(y-z)(y-10)
Answer:
x = - 3
Step-by-step explanation:
x² - 5 = 4
x² = 4 + 5
x² = 9
x = ± 3
the negative solution
x = - 3
