The function is open up for both since the stretch value is positive. When opening you we don’t have a maximum value only a minimum value. So already we know B and d are wrong. When looking at minimums and maximums we look at the y or q value. In this case for f(x) it is 4 and for g(x) it is 5. So we know g(x) have a greater minimum value, so the answer is c

Please help me with a geometry problem, I don't understand.
Goshia [24]

The slope-intercept form:

y=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

m - slope

b - y-intercept

We have the points (1, -5) and (9, 11). Substitute:

m=\dfrac{11-(-5)}{9-1}=\dfrac{16}{8}=2

Therefore we have

y=2x+b

Put the coordinates of the point (1, -5) to the equation:

-5=2(1)+b\\\\-5=2+b\qquad\text{subtract 2 from both sides}\\\\-7=b\to b=-7

<h3>Answer: y = 2x - 7</h3>
