PLZ HELP The next slide has the function f (x) = x² graphed in
red. The function f(x) = ax_ is graphed in blue. Use
Slider a to investigate the effect a has on the parent
function f(x) = x2
Answer below.
1. What happens when a is positive?
2. What happens when a is negative?
3. What happens as ſal becomes larger?
4. What happens when 0< lal <1?

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

no

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
