Please help how do I find this on a graph.
y-intercept = 1 ; slope = 1/2

Start on the point (0,0) and go right twice and up twice.

Step-by-step explanation: The y-intercept is what number the line crosses over on the y axis, and the slope is rise over run so go up once and over twice.

to vertically strech a function by a factor of c, multiply the whole function by c

so

f(x) vertically streched by a factor of 4 is 4f(x)

so we get

the new function is f(x)=4(2)ˣ
