Practice problem
Which of the following are examples of vertical stretches to the function f(x)=12x2+3x+4f(x)=12x^2+3x+4f(x)=12x2+3x+4?
f(x)=2×12x2+3x+4f(x)=2\times12x^2+3x+4f(x)=2×12x2+3x+4
f(x)=18x2+4.5x+6f(x)=18x^2+4.5x+6f(x)=18x2+4.5x+6
f(x)=6x2+1.5x+2f(x)=6x^2+1.5x+2f(x)=6x2+1.5x+2
f(x)=24x2+6x+8f(x)=24x^2+6x+8f(x)=24x2+6x+8
Type a concept, like “slope” or “photosynthesis”.
