# Factorise [8x^{2}-30x-27=0

## Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

8x² - 30x - 27 = 0

8 = 4 * 2

-27 = -9 * 3

-30 = 4*(-9) + 2*3

so (4x + 3)(2x - 9) = 0

### Answers

Answer:

• first one:

f(x) approches -∞

we can see clearly in the graph that the function is decreasing toward infinity

• second one:

f(x) approches 1

we can that y=1 represents an asymptote

f(x) is growing toward 1 without reaching it

### Answers

Answer:

112

Step-by-step explanation:

Difference between each 4,8,7,5,1

Add numbers next to each other in pairs = 12

So 12-1= 11 and

Find the x-values (if any) at which f is not continuous. Which of the discontinuities are removable? (Enter your answers from smallest to largest. Enter NONE in any unused answer blanks.) f(x) = x + 3 x2 − 2x − 15

### Answers

Answer:

-3 (removable), +5

Step-by-step explanation:

Maybe you have ...

This will have discontinuities (points where the function is undefined) at ...

• x = -3
• x = 5

The discontinuity as x = -3 is removable by defining f(-3) = -1/8.

### Final answer:

The function f(x) = x + 3x² - 2x - 15 is continuous for all x-values.

### Explanation:

In order to find the x-values at which the function f(x) = x + 3x² - 2x - 15 is not continuous, we need to look for points where the function has discontinuities. A function can have three types of discontinuities: removable discontinuities, jump discontinuities, and infinite discontinuities.

To find the x-values at which f(x) is not continuous, we need to check for three conditions: 1) The function is defined for all real numbers, so there are no points where f is undefined. 2) The function does not have any jump or jump-like discontinuities, which occur when the left and right limits of a point are finite but not equal. 3) The function does not have any infinite discontinuities, which occur when the left and right limits of a point are infinite.

Therefore, the function f(x) = x + 3x² - 2x - 15 is continuous for all x-values. There are no discontinuities in this function.
