Answer:

A. y = cos x

Step-by-step explanation:

The function that we see graphed has the point (0,1), this means whichever trig function f(x) it represents f(0) = 1.

Now, only the cosine function has the property that cos(0) = 1, thus choice A is the correct answer.

Step-by-step explanation:

Step 1: Define

g(x) = x³ - 4

h(x) = x² + 2

h(-2) is x = -2

g(-1) is x = -1

Step 2: Find h(-2) - g(-1)

Substitute: ((-2)² + 2) - ((-1)³ - 4)
Exponents: (4 + 2) - (-1 - 4)
Add/Subtract: 6 - (-5)
Subtract: 11

Two numbers add to be 5 multiply to be -6

FrozenT [24]

Answer:

-1, 6

Step-by-step explanation:

x + y = 5

xy = -6

Take first equation and rewrite it. y = -x + 5

Then substitute the new equation in the second one.

x(-x + 5) = -6

-x^2 + 5x + 6 = 0

Divide by -1

x^2 - 5x - 6

(x + 1)(x - 6) = 0

x = -1, 6
