Answer:
x
=
√
y
+
5
3
Explanation:
To find the inverse of a function expressed as
XXX
y
=
an expression in
x
rearrange the expression into the form:
XXX
x
=
an expression in
y
Given
XXX
y
=
3
x
2
−
5
Switch sides and add
5
to both sides
XXX
3
x
2
=
y
+
5
Divide both sides by
3
XXX
x
2
=
y
+
5
3
Take the square root of both sides
XXX
x
=
±
√
y
+
5
3
Since we were asked for an inverse function, I've eliminated the non-primary root (a function can not have two values for a single argument value).
Therefore
XXX
x
=
instead of Y do G
Step-by-step explanation:
Answer:
Step-by-step explanation:
step 1
Find the slope m
The formula to calculate the slope between two points is equal to
we have the ordered pairs
(10,5) and (2,-3)
substitute the values
step 2
Find the equation of the line in slope intercept form
we have
substitute and solve for b
The linear function is equal to
Step-by-step explanation:
The answer is - 4
Because when you solve it
x2 - 16 = 0
x2 = 16
So we will square root it
x = - 4
One more thing don't you have the option x = 4
