F(x) = x^-1, x=.9. Use linear approximation to estimate answer

Mathematics

Angelina_Jolie [31]3 years ago

L(x) = f'(a)(x - a)
f(x) = x^(-1), f'(x) = -x^(-2)
Let a = 1, f'(a) = -(1)^(-2) = -1
L(0.9) = f'(1)(0.9 - 1) = -1(-0.1) = 0.1

Therefore, linear approximation of f(x) = x^(-1) for x = 0.9 is 0.1

The line passes through the point (-7,-5) and has slope of -8
stira [4]

Answer:

y=-8x-61

Step-by-step explanation:

The slope-intercept form of the equation is y=mx+b where m is the slope and b is the y intercept. We know so far, that the slope is -8. We plug that in for m.

y=-8x+b

Now, we need to find the y-intercept. The question gives us the point (-7,-5). We plug in -7 for x, and -5 for y.

-5=-8(-7)+b

Then, we solve.

-5=56+b

Subtract 56 from both sides.

-61=b

Finally, we get this equation:

y=-8x-61
