Mathematics
1 answer:
lianna [129]3 years ago
4 0

Answer:

D=41

Step-by-step explanation:

4x² + 3x − 2 = 0

To find the discriminant we need to use formula

D = b² - 4 ac

Quadratic equation in general form:

ax² + bx + c = 0

4x² + 3x − 2 = 0

We can see that

a = 4, b = 3 , c = -2

So, D = 3² - 4*4*(-2) = 9 +32 = 41

D = 41 is positive , so given equation has 2 real solutions.

If D = 0 , there is  1 real solution.

If D< 0 , then there is no real solutions.

PLEASE HELP!! Which equation matches the table of values?
RoseWind [281]

The equation that represents the table of values is y=(\frac{1}{4})^x

Step-by-step explanation:

We need to find the equation that matches the table of values.

x y

0 | 1

1 | 1/4

2 | 1/16

3 | 1/64

So, when x =0 y=1 and when x=1, y=1/4

if y=(\frac{1}{4})^x

then putting x=0 we get y=1

x=1, we get y=1/4

x=2, we get y=1/16

x=3, we get y=1/64

So, the equation that represents the table of values is y=(\frac{1}{4})^x

Kindly check your options, as option D should be y=(\frac{1}{4})^x
