$f (x) = x^{2} - 7$ , $a = 7$

Step 1

Use the slope-intercept form to find the slope.

Step 1.1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 1.2

Using the slope-intercept form, the slope is Undefined.

$m = Undefined$

Undefined

Step 2

Since the slope of the equation $a = 7$ is undefined, there is no tangent line for $f (x) = x^{2} - 7$ which is parallel to $a = 7$ .

No tangent line can be found
