Question

Using the calculator to find the important points:F (x) = -x^2 + 3x Example: F (x) = 2x^2+14x+27Vertex: (-3,5 , 2,5) ans: x = -3,5No x - intercept

Answer 1

`F\mleft(x\mright)=-x^2+3x`

vertex:

`\mleft((3)/(2),\: (9)/(4)\mright)`

intercept:

`x-\text{intercept (0,0),(}3,0)`

x:

`x=(3)/(2)`
