Which of the following is a function equivalent to f(x) = 4(1.8)2x?

f(x) = 4(3.24)x

f(x) = 4(3.24x)

f(x) = 12.96x

f(x) = 51.84x

1/3 + 1/5 = 8/15.

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
