The function  y = 4 − 16x2  intersects the x-axis at the following values of x.

Given f1x2 = 3x + 1 and 1f + g2 1x2 = 6 - 12 x, find the function g.

For the function y = 3x2 + 9x + 4, at the point x = 8, find the following.

Calculate the values of x for which the function y = -3x² + 4x + 2 is strictly decreasing.

Graph the function. f(x) = −x2 + 3

Determine g(x+3) for the following function.  g(x)=4x2−3x+5

Given the function, identify the x-intercept if any
