<u>Answer:</u>

The range of the function y = 2cos x is -2 <y < 2 .

<u>Step-by-step explanation:</u>

We know that cos (0) = 1 and cos (π) = - 1 are the two extreme values which cos x assume when x ∈ R and it is also that cos (x) is a continuous periodic function with period 2π when x ∈ R ,

since ,

cos (x + 2π) = cos x

So, the range of the  function y = 2cos x is -2 <y < 2 .

Alla [95]

Answer:  the  y-intercept is -7

Step-by-step explanation:  Rewrite the equation in slopr intercept form and simplify:

2x-5y=35   Subtract 2x from both sides

-5y = -2x + 35    Divide both sides by -5 to isolate y
