Answer:
y = 20*4^x
Step-by-step explanation:
to find the value of the constants a and b, we just need to use the points given in the equation and solve the system of equations:
point (0,20): x = 0 and y = 20:
20 = a*b^0 = a*1 = a
a = 20
point (2,320): x = 2 and y = 320
320 = 20 * b^2
b^2 = 16
|b| = 4
b = 4 or b = -4
So we have two exponencial equations that pass through these points:
y = 20*4^x and y = 20*(-4)^x
As the questions asks for just one equation, we can answer y = 20*4^x
Answer:
Step-by-step explanation:
First, you description of ^ is very well written as well as being correct.
Second: all you can do is combine the 6 and 28. They are like terms
34 - c^3
That's as much of an answer as you can get.
Step-by-step explanation:
4x³ - 14x² + 12x
= 2x[2x² - 7x + 6]
= 2x[(2x-3)(x-2)]
= 2x(2x-3)(x-2)
Answer:
A parabola is continuous but for y to be function of x the axis must be parallel to the y axis and for x to be a function of the y axis must be parallel to the x axis
