a. Which graph represents which function? Explain your answer, please.
b. How many solution does the equation 0,52x^4 = 17 have?
c. Show that h(2a) = 4a^3
d. Give the domain and the range of function g
e. Given is the function k(x) = -1 1/2 + 2 √ax+b. Calculate the value of a and of b
The first two look like normal polynomials to me.
if the highest power is even then the ends will both be above or both be below the x axis.
if the highest power is odd then one end will be above the x axis and one below. (both heading off to + or - infinity)
The last one looks like it could be a part of a Sideways parabola.
Now you tell me which is which. And you tell me why you think so.
Please no one answer over me.
