What the answer to this

C = 5x^3 -2

Step-by-step explanation:

the greater the coefficient above 1 the more narrow the graph, so that would have to rule out 0.2. And the graph hasn't been reflected in the x axis, so then that means that it has do be C

it’s the C f(x) =5x3-2

Step-by-step explanation:

Basically if you replace x by 0, you will find as an answer -2 if you check in the graph.

And when you replace x with 1, you find 3 on the graph. So since you know that the equation should contain -2 for sure, you take a look at the 2 last, ignoring the A and B. So then you start by replacing x by 1 for the C but this time in the equation not graph : f(1)= 5-2=3 which is the same answer you read on the graph, so it’s the answer C.

i dont know

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
