Answer:
a = 11 , b = 4
Explanation:
to find a and b substitute the coordinates of the given points f(x) passes through into f(x)
f(x) = a
substituting (0, 11 ) into f(x)
11 = a
[
= 1 ] , then
11 = a
f(x) = 11
substituting (2, 176 ) into f(x)
176 = 11b² ( divide both sides by 11 )
16 = b² ( take square root of both sides )
= b , that is
b = 4
thus a = 11 and b = 4 and
f(x) = 11
