This table shows some values of an exponential function.
x | y
0 | 0.25
1 | 1.25
2 | 6.25
3 | 31.25
what is the function?

A. f(x) = 5(0.25^x)
B. f(x) = 0.25(1.25^x)
C. f(x) = 0.25(5^x)
D. f(x) = 0.25(1/5)^x

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

i have no

- 4, v72, 32/5

i think this is right.

hope it
