Find the average rate of change of f(x)=4x^2-7 on interval [1,b]

Given: hf || jk; hg ? jg prove: fhg ? kjg to prove that the triangles are congruent by asa, which statement and reason could be used as part of the proof? fgh ? kgj because vertical angles are congruent. jkg ? hfg because vertical angles are congruent. fhg ? jkg because right angles are congruent. hfg ? kjg because alternate interior angles are congruent.

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!

The functions f(x) and g(x) are shown in the graph f(x)=x^2 what is g(x) ?
