| True or False? <br>f(x) means f*x | False. f(x) is a special symbol used to denote a function. It's read f of x.
🗑
|
||||
| True of False? <br>The square root of a negative number is NOT a real number | True. No real number, when squared, will equate to a negative number.
🗑
|

| Is the function f(x)=3x<sup>2</sup> linear? | No. This equation cannot be written Ax+By=C and therefore its graph is not a line.
🗑
|
||||
| When comparing the functions g(x)=x<sup>2</sup>+10 and f(x)=x<sup>2</sup>, do you find a horizontal or vertical shift? Is the shift up, down, left or right? | Since the addition is being done AFTER the squaring is done, the shift is UP by 10.
🗑
|
||||
| Which function will give you a V shaped graph? <br>f(x)=x<sup>2</sup> or f(x)=|x|? | f(x)=|x|
🗑
|

| In the linear equation y=mx+b which variable represents the slope? Which variable represents the y-intercept? | m=slope, b=y-intercept
🗑
|
||||
| Which form is <br>y = mx + b? | Slope intercept form.
🗑
|
||||
| Does the following equation represent a horizontal or vertical line? y=c | Horizontal.
🗑
|
||||
| What do we know about the two lines if the product of their slopes is -1? | The lines are perpendicular.
🗑
|

| Re-write y=3x-1 using function notation. | f(x)=3x-1
🗑
