The formula for an exponential equation is y = a * b^x with a and b being a fixed value.

"a" would also be the Y intercept, which is where the graph touches or crosses the Y axis. In the given graph, the curved line touches the Y axis at 100, so the value of a would be 100.

Now we need to find b.

The blue dot at Y 50 is lined up with x = 1, so we can use the point (1,50)

Using the X and Y values we can solve for b:

format: y = a * b^x we replace the letters with the numbers above:

50 = 100 * b^1

b^1 = b so now we have:

50 = 100 *b

Divide both sides by 100 to get b by itself:

b = 50/100, which reduces to 1/2, so b = 1/2

So the equation of the graph becomes y = 100(1/2)^x

You may need to write the 1/2 as 0.5, not sure how you need to enter it.

What type of roots will you have if the discriminant is: 36
Paul [167]

Answer:

2 real roots

Step-by-step explanation:

If the discriminant is any positive number, that means the quadratic will have 2 real roots, or solutions.

Since the discriminant, 36, is a positive number, this will apply.

So, if the discriminant is 36, there will be 2 real roots.
