Find the axis of symmetry and the vertex of the graph of f(x) = 4x^2-8x+3.

(1, -1) and x= -1

Step-by-step explanation:

The vertex is (1, -1)

The parabola params are:

a=4, b=-8, c=3

v= −b/2a

- (−8)/ 2 · 4

Simplify

v=1 v=1

Plug in v=1 to find the y value

y=−1

Therefore the parabola vertex is

(1, −1)

The axis of symmetry is the line that passes through the vertex and focus.

Therefore, your axis of symmetry is

x= -1

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
