What are the coordinates of the vertex of the graph of the given function? y=-4x^2+3

The coordinates of the vertex of the graph of the given function y=-4x^2+3 is ( 0 , 3 ) when x = 0 , y is the largest when x = 0 , y = -4*0^2 + 3 = 3 so the coordinates of the vertex is ( 0 , 3 ) .

The coordinates of the vertex of the graph of the given function y=-4x^2+3 is ( 0 , 3 )

when x = 0 , y is the largest

when x = 0 , y = -4*0^2 + 3 = 3

so the coordinates of the vertex is ( 0 , 3 ) .

when x = 0 , y is the largest

when x = 0 , y = -4*0^2 + 3 = 3

so the coordinates of the vertex is ( 0 , 3 ) .

2x^2 - 5x = 12;

2x^2 - 5x - 12 = 0;

(2x + 3)(x - 4) = 0;

2x + 3 = 0; 2x = -3; x = -3/2;

x - 4 = 0; x = 4

x = -3/2 or x = 4

2x^2 - 5x - 12 = 0;

(2x + 3)(x - 4) = 0;

2x + 3 = 0; 2x = -3; x = -3/2;

x - 4 = 0; x = 4

x = -3/2 or x = 4

Solve by factoring. 4a^2-4a=15
**Weegy:**
4a^2 - 4a = 15;
4a^2 - 4a - 15 = 0;
(2a + 3)(2a - 5) = 0;
2a + 3 = 0; 2a = -3; a = -3/2;
2a - 5 = 0; 2a = 5; a = 5/2
a = -3/2 or 5/2

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. d^2-4d-96=0
**Weegy:** Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. [ d^2-4d-96=0
Answer d? - 4d - 96 = 0
The quadratic formula is
************_______
x = (-b ? ? b? - 4ac)/2a
For this equation, a = 1, b = -4, c = -96
************_________
x = (4 ? ? 16 - ( -384)) / 2
x = (-1 ? 20)/2
x = -8 , 12 ?
r? - 35r + 70 = 0
a = 1, b = -35, c = 70
************_______
x = (-b ? ? b? - 4ac)/2a
*************_________
x = (35 ? ? 35? - 4(70))/2
**************___
x = (35 ? 3?105)/2
x ? 2.13 , 32.87 (Both are rounded to the hundredths place) ] **User:** Identify a, b, and c in the given quadratic equation.

The solution for d^2 - 4 - 96 = 0 is d = 12 ,or d = -8 .

d^2 - 4d - 96 = 0

(d - 2)^2 - 4 - 96 = 0

(d - 2)^2 = 100

d - 2 = 10

d = 12

or

d - 2 = -10

d = -8

d^2 - 4d - 96 = 0

(d - 2)^2 - 4 - 96 = 0

(d - 2)^2 = 100

d - 2 = 10

d = 12

or

d - 2 = -10

d = -8
