2. What percentage of illnesses are linked to stress? \( 50-70 \) percent \( 10-20 \) percent \( 20-30 \) percent \( 40-60 \) percent

4. Given \( f(x)=x^{2}-49 \), Find \( \frac{f(x+h)-f(x)}{h} \)

Write three integers that do not have all the same sign (you shou d have at leas negative number) that have a sum of -8 Draw a chip model to prove it

Let \( f(x)=\frac{14 x^{4}+a x^{2}+b}{7 x^{4}+c x^{2}+d} \), where \( a, b, c \), and \( d \) are unknown constants. Which of the following is a possible graph of \( y=f(x) \) ? Dashed lines indicate asymptotes.

d. \( \frac{1}{2}-\frac{1}{3}=1-\frac{5}{8} x \)
