f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.

Step-by-step explanation:
Write H(t) for the total sum spent in the United States on health care in year t, where t is measured in years since 2000.
The rate of increase of H(t) was projected to rise from $100 billion per year in 2000 to approximately $190 billion per year in 2010
(a) Find a linear model for the rate of change H'(t)
Slope of line is (190-100)/(2010-2000) = 90/10 = 9 billion dollars per yr
H'(t) - 190 = 9 (t-10) =
H'(t) = 9t + 100 billions dollars per year
(b) Given that $1,300 billion was spent on health care in the United States in 2000, find the function H(t).
H'(t) = 9t + 100 billions dollars per year TAKING INTEGRATION..
H(t) = 9t^2/2 + 100t + C given H(0) = 1300
H(0) = 1300 = C
H(t) = 9t^2/2 + 100t + 1300 billion dollars.
