frez [133]

Answer:

tanx = 1

Step-by-step explanation:

I assume you mean sinx = cosx

In this case we have to recognize that tanx = sinx / cosx

So if we divide cosx over we can get tanx

So:

Cosx divided by itself gives us 1

sinx / cosx = 1

tanx = 1

Identity Structure find the rule for each function table.

Andreyy89

Answer:

The rule for given table is y = 4x - 1.

Step-by-step explanation:

From the given table it is noticed that the function passing through the points (1,3), (2,7) and (3,11).

If a line passing through the two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The equation of line is

$y-3=\frac{7-3}{2-1}(x-1)$

$y-3=\frac{4}{1}(x-1)$

$y-3=4(x-1)$

$y-3=4x-4$

Add 3 both sides.

$y=4x-4+3$

$y=4x-1$

Therefore the rule for given table is y = 4x - 1.
