Answer:
a=3
Step-by-step explanation:
N.B: I don't see any k. hence solving for a
The graph is a parabola.Thus the parent function [tex]p(x)=x^2[/tex]. Notice p(x) has been stretched vertically by a units impling a is a positive constant. We want to find a . Let's pick a point (1,3). we already know that p(x)=x² . so substitute 3 for r(x) and 1 for x and then solve for a. [showed below]
[tex]r(x) = a \cdot p(x) \\ \implies 3 = a \cdot 1 \\ \boxed{a = 3}[/tex]
