WebBy comparing the given equation and standard form, we get a = 3. b= 12, c = -12. We know that the vertex formula is (-b/2a, -D/4a) We know that D = b2 – 4ac. Therefore, D = (12)2-4 (3) (-12) D = 144+144 D = 288. Now, substitute all the known values in the formula, we get Vertex, (h, k) = ( (-12/2 (3)), (-288/4 (3)) (h, k) = (-12/6, -288/12) (h. WebGraphing Logarithmic Functions. We will graph a logarithmic function, say f (x) = 2 log 2 x - 2. We will graph it now by following the steps as explained earlier. Its domain is x > 0 and its range is the set of all real numbers (R). To understand this, click here. Its x-int is (2, 0) and there is no y-int.
