The function LaTeX: f\left(x\right)=2\cdot5^xf ( x ) = 2 ⋅ 5 x can be used to represent an exponential growth curve. Which of the following points is NOT on the curve? (3, 250) (2, 20) (1, 10) (2, 50)

(2,20)

Step-by-step explanation:

The given function is

To see which point is not on this curve, we must substitute the points to see which does not satisfy the equation;

For the first point we substitute x=3 and f(x)=250

This is true.

For the second point (2,20), we put x=2 and y=20 to get:

This is false, hence (2,20) does not lie on this curve.

For (1,10), we have:

This is also true

Finally for (2,50), we have;

This is also true.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
