Idently the graph of f(x) = 3(x - 1) - 4. Then identity the vertex and ads of symmetry find the minimum value of and describe wh
Vesna [10]

Answer:

See below

Step-by-step explanation:

I assume you mean f(x) = 3(x-1)^2-4

The equation is already in vertex form f(x)=a(x-h)^2+k where a affects how "fat" or "skinny" the parabola is and (h,k) is the vertex. Therefore, the vertex is (h,k)\rightarrow(1,-4).

The axis of symmetry is a line where the parabola is cut into two congruent halves. This is defined as x=h for a parabola with a vertical axis. Hence, the axis of symmetry is x=1.

The minimum value is the smallest value in the range of the function. In the case of a parabola, the y-coordinate of the vertex is the minimum value. Therefore, the minimum value is y=-4.

The interval where the function is decreasing is (-\infty,1)

The interval where the function is increasing is (1,\infty)

Simplify 7.32a+2.1∙(2.7−18a)
tresset_1 [31]
7.32a + 2.1(2.7 -18a)
7.32a + 5.67 - 37.8a (multiply 2.1 to 2.7 and 18a)
5.67 - 30.48a (combine 7.32a and -37.8a since they are like terms)
