↳Redirected from "Suppose that I don't have a formula for #g(x)# but I know that #g(1) = 3# and #g'(x) = sqrt(x^2+15)# for all x. How do I use a linear approximation to estimate #g(0.9)# and #g(1.1)#?"

#$32482.52#

Explanation:

So for questions like this, I prefer to use the unitary method which is to find 1% then times that by 100 to find 100%.

here's how:

#33,457 = 103%(100%+3%)# this is because it is 3% more than what she earned before so it becomes 103%

#(33,457)/103 = 1%#

#100 = (33,457)/103 * 100#

#100 % = 32,482.5242718447#

since it is money we round to 2 decimals.

so the answer is #$32482.52#

Let.. her last year salary be #x#
Three percent more means is #3%# more than last year
It means it is #100%+3%=103%# more than last year
#x xx 103/100 = 33457#
It means
#x=33457xx100/103#
Multiply
#x~~32482.52#
