Based on the graph below, what are the solutions to the equation f(x) = g(x)?
x = -3.7, 0.5, 3.4 x = -1, 1, 2 x = -2, 2, 3 x = -2, 0.6, 3.4
@ninjasandtigers
do you know what the functions are?
nope
it just said f(x)=g(x)
you see the point where f(x) crosses g(x)?
yes
those are your solutions
ya but it doesnt match the choices
it matches d
ok thanks
welcome
i have one more
The table below shows the values of f(x) and g(x) for different values of x. One of the functions is a quadratic function, and the other is an exponential function. Which function is most likely increasing quadratically?
x f(x) g(x) 1 3 3 2 6 9 3 11 27 4 18 81 5 27 243
f(x), because it grows faster than g(x) g(x), because it will not intersect f(x) g(x), because it grows slower than f(x) f(x), because it grows slower than g(x)
i want to say f(x) is the quadratic because g(x) is growing exponentially
so i think d
ok thank you and i have one more and this is the last one
Emily wants to hang a painting in a gallery. The painting and frame must have an area of 31 square feet. The painting is 5 feet wide by 6 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?
4x2 + 22x - 1 = 0 4x2 + 22x + 31 = 0 x2 + 11x - 1 = 0 x2 + 11x + 31 = 0
the outer dimensions would be 2x+5 and 2x+6
so what would the answer be
4x^2+22x+30=31
did you get it?

yeah thanks
