Question

determine the x-intercepts for f(x)=3(x-2)^2-3 and g(x)=2x^2+8x+6

Answer 1

you are expected to solve for 3(x-2)^2 - 3 = 0 which gives the x-intercept

(x-2)^2 = 1, x -2 = +/- 1, x = 1 or 3

for 2x^2 + 8x +6 = 0

x^2 + 4x + 3 = 0 or (x+3)(x+1) = 0, so the answer is x = -1 or -3

Answer 2

f(x)=x-4 'g'(x)=X=3

Answer 3

f(x)=x-4 'g'(x)=X=3

Answer 4

(x_2)^=1,x_2=+/_1=1 or 3

for2x^2+8x+6=0

x^2+4x+3=0 or(x+3)(x+1)=0,so the answer is x=-1or-3

Answer 5

6+2x=2x-2

Answer 6

The function F(x) is a line. If the slope of f(x) is 2/3 and f(1)=1, then find f(3/2)

Answer 7

the annual average income y of an american man over 25 with an associates degree is approximated by the linear y-653.6x+27593.9, where x is the number of years after 2000. Predict the average income of an american man with an associate's degree in 2009.
