Fill in the blank that will give the correct output!

If f(x) = 2x+1, then f(___)=13

If f(x) = 2x² + 5x - 3, evaluate f(-1).

• f(-1) = 0

• f(-1) = 6

• f(-1) = -10

• f(-1) = -6

• f(-1) = 10

The function h(t) represents the height in inches of a plant after t weeks. What does the notation h(4) = 5 mean?

• After 5 week the plant is 4 inches tall

• The plant grows at a rate of 5/4 inch per week

• After 4 weeks the plant is 5 inches tall

• The plant grows at a rate of 1 inch per week

−8⋅f(0)+4⋅g(−8)=

Let 𝒇(𝒙) = 𝟔𝒙 − 𝟑, and let 𝒈(𝒙) = 𝟎.𝟓(𝟒)^𝒙 . Find the value of each function for the given input:

𝒇(𝟔) − 𝒇(-𝟐) = ?

−6⋅f(−3)−5⋅g(−7)=

Let 𝒇(𝒙) = 𝟔𝒙 − 𝟑, and let 𝒈(𝒙) = 𝟎.𝟓(𝟒)^𝒙 . Find the value of each function for the given input:
