Graph the function f(x) = cos(2x) +1

ANSWER

See attachment

EXPLANATION

We know how to graph

The given function

is obtained by transforming the graph of

The period is π.

Hence we graph cos(x) such that it completes one cycle after every π units and then shift this graph up by 1 unit to obtain

The amplitude is 1.

Hence it's range is

0≤y≤2

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
