Find the area of a triangle bounded by the y
axis, the line
f
(
x
)
=
6
−
2
7
x
, and the line perpendicular to
f
(
x
)
that passes through the origin.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

Wait what the question
