Find the solutions of the equation in the interval [−2π, 2π]. Use a graphing utility to verify your results. (Enter your answers as a comma-separated list.) sec(x) = − 2 3 3

idk

step-by-step explanation:

do it yourself, cause that made me do it myself today, in english!

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

ok so what's the question?

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
