You are given the exponential function g(x) = 3 x . which option below gives the formula for a new function h created by stretching g by a factor of 3 along the y-axis? h(x) = 3x+1 h(x) = 3x-1 h(x) = x · 3x+1 h(x) = x · 3x-1

The correct option is (b)

Step-by-step explanation:

h(x) = 3x+1

h(x) = 3x-1

h(x) = x · 3x+1

h(x) = x · 3x-1

a² + b²= c²

24² + 7² = c²

c= 25

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
