Given f(x) = 5x + 3, what is the value of f(2)?

Find the value of h(5) if h(t) = $$2t^2+t$$ .

Zach King is a new content creator on TikTok. His followers are gradually increasing and can be calculated using the function F(d) = $$d^2+30d$$ , where d is the number of days Zach has been on TikTok. Based on this model, how many followers will Zach have on day 10?

Given $$h(t) = -t^2+7t$$ , what is h(4)?

Given g(x) = 3(1 − x), what is the value of g(−2)?

Given C(n) = $$\frac{1}{2}n-5$$ , what is the value of C(20)?
