Equation of a Tangent Line: Find the standard (slope-intercept form) equation of the tangent line to the following functions at the specified points.(Use method 1)

problem no.4

Method 1
m = lim (x)-f(a)
x→a
х-а
Where: m = slope
f(x) = given function
a = point of tangency at x=a
f(a) = function evaluated as "a"
Transcribed Image Text:Method 1 m = lim (x)-f(a) x→a х-а Where: m = slope f(x) = given function a = point of tangency at x=a f(a) = function evaluated as "a"
1. f(x) = x² – 4x + 1 at point (0,1)
2. f(x) = x³ + 2 at point (1,3)
3. f(x) = 2x* + 3x³ – 2x + 7 at point (-1,8)
4. f(x) = v2x + 7 at x = 1
